Hm, strange. Maybe because I don't use a crappy low-end card? Turbocache&co sucks in a lot more ways than just beryl-support. Your own fault if you bought something like that.

Stop behaving like a whiny ass. If you use beta software and alpha-features, bugs are a normal result.

Energyman76b,

Your reply is very inappropriate and please show some respect for other users that participate in this forum.

I have a new nvidia gts 8800 320 mg. I run suse 10.2. and beryl. I am using 9755 drivers. My computer is on all the time. Sometimes in the middle of productive work the black windows show up. I followed step by step nvdia instructions. I even reinstalled clean suse 10.2 without any options and I installed the driver and the black window came back. I have new equipment and fx-55 amd cpu 2GB of memory and I do not run games. Nvida card works perfect in 2D but not with beryl. Beryl works perfect in a laptop with intel chip.

Since I introduced the changes indicated by Jim 255 I have not had any black windows (1 week running time), the system is very stable, and I can run everything including mythtv in a whole screen in one side of the cube.
Maybe many of the changes are unnecessary or even may decrease performance but at least some of the changes are very valid and make beryl usable and very responsive, which it was not following nvidia instructions.

There are very basic rule to determine if a bug exist or not

1. many users have it
2. can be reproduce
3. can be trace to a device, driver, program in such a way that if you remove it the bug is not there
4. The final proof is if it can be fix ;-)

Seems almost all of them are here. The fact that you may not have it, it is typical of bug reporting. Many difference could between your system and the rest of us that have it.
I wish as Jupiter tha nvidia may fix it. I am sure that they are working on it. Nvida is superb and responsible company. Often when fixing a bug you create few more bugs. Sometimes you may have problems in hardware design that make the bug fixing very hard. I do believe this thread is very important accomplishing two functions: 1) allowing the people with the bug being able to corrected it, or better say patch it until a final solution is obtain 2) help Nvidia to find the final solution.

In my part I will keep trying help Jim to determine what option are important, detrimental or unnecessary at least for my video adapter version.

Have a good weekend

Hi Jupiter,

Have you being able to eliminate the black window bug in your system?
You mark many options that may be unnecessary or even worst, decrease performance but which is the one that prevents the bug from showing?
If we can separate that, then we can add one by one and see the effects. I am aware that all nvidia cards are not the same but with so many users in this thread we may be able to get some meaningfully data.
As I said before I tried all the tips that I found including the ones in the bery forums and nothing did it until #255.

Heya terryxela
No. After doing some testing I am able to reproduce the bug after
pushing my computer to extremes. As stated in one of my previous post.

with flash animation going on all. I opened 10 konqueror file managers with
10 tabs each. I then opened 4 movies at the same time. I then ran a ltrace
session on compiz. After that i finally ran out of memory and got the bug.
So yes it effects my setup too.
This is not normal computer use for me, but i wanted to see how
far i had to push it to get the bug. Under normal daily use which
includes running the new merged Compiz/Beryl named CompComm,
I never see the bug. For the test, i was running the latest Beryl.
I did the test with Beryl because that is what the majority of people
have and, i didn't want to introduce any anomilies that may occur
from the very alpha CompComm.

I use a custom kernel and Gentoo 2007 completely tweaked for
performance. I have all plugins enabled in Beryl including blur. I
use cvs rev of nvclock "soon to be released beta3" because it allows
me to adjust the fan on my hot 8800. And it also reads temps on
the 8800. By the way this beta3 also works with all 8000 series cards.
EDIT: i am also using nvclock to adjust vsync and AA/FSAA, so i don't
even have to use nvidia-settings.

Yeah a lot useful!!
You should put your high-end card into your ass as well as your opinion too!!
And don't write again here cause guys like you make me sick!!

@Jupiter:
RENDER extension is not RenderAccel option!! Don't get comfused... and it is not enabled by default as well as DAMAGE extension too! These are Xorg's stuff not nvidia's driver!!
Also your system is not a good testing machine for the problem cause your vRAM is huge and it is also too powerful to notice small performance changes

We are working here with normal systems that most of us have.

But I want to thank you very very much for your help and I just edited the new #329 post according to some of your words in your last post!!

Jim and Jupiter,

In reference to AIGLX I agree so far with Jupiter. I tried both true and false as well as nothing. All load nvdia. I also tested the FPS over a minute and I did not see any significant changes so in my video adapter (GLS 8800 320MB) it does not make any difference if it is there or not neither affect performance if it is flag as true. So the nvidia default of nothing written with reference to AIGLX under "ServerLayout" seems to be correct.

Have all of you a good weekend

Yea i believe you are correct. And as far as my machine not being a good
test bed, as far as performance, again you are correct. But people with
8000 series cards are also having the black window bug, so i thought i
would try and help because i am not seeing it under normal use.

Thanks for clearing things up though. I am most definitely dependent on
you guy's for help with this bug, so i can help my user's, so keep up the
good work and all the research you guy's have been doing.

Hi people,

I was just wondering if anyone knows if the latest Nvidia beta (100.14.06) fixes or improves the Black Windows Bug.

I noticed the beta claims "Impoved Notebook support", so the question is, is it worth me installing it?

Hello Jarocooke welcome to our thread!!

The Bug is haunting this driver too!!
Not worth updating to it at all except if you have an 6 series card and face a bug in KDE with slow typing if fonts are antialiasigned!
I have also faced troubles with this driver, video freezes when trying to shutdown system and stops everything sometimes!!
If it continues I 'll downgrade to good old 9755 which has the same problems but it is more stable!!

Tell us what's your experience with post's #329 settings...

Default Re: beryl black windows bug

Hi djfoo, this post is for you.

I encountered this black window bug recently. I find it strange cause the bug didn't occur on my system earlier.(I bought this old 6800 GT 256 ram for less than 2 months, previously an ati card which really sucks...)

Heres my desktop pc specs:
AMD x2 3800+
2 GB RAM
20" LCD 1680x1050
Nvidia beta 100.14.06 (update from last 03 driver and i get 500fps+ in glxgears)
Suse 10.2

I tried the settings you posted. I think it's overkill and slow the system down.
I agree with Jupiter1tx for the AIGLX setting. When I run beryl from terminal it detects as Nvidia not Aiglx.
My xorg.conf is pretty much the same as Jupiter1tx. I'm running a typical kde desktop.
I tried to use glxgears for measuring performance (I know glxgears is not very accurate but well at least it's a benchmark...).
Nvidia with no beryl running I get 11000fps
With beryl running it's about 70% of the frame rate above.
* With AIGLX I only get 14% out of 11000fps!!
With 'use copy' it's about 43% but my dual core cpu runs very high!! (80%+ usage)
'No Cow', Xgl binding, Indirect rendering all get about 72%.
For your combo settings I get 22%

I also run a 480p quicktime video full screen with mplayer for cpu usage.
beryl is supposed to take care of all the graphic process. aiglx, no cow,
xgl binding and indirect rendering consume my cpu usage abit higher than the original beryl auto setting. As for 'copy' that's simply unusable.

One thing that's very important for me is the 'tearing' issue visible on video playback. Non beryl and beryl desktop show no tearing on video playback at all. But if my system is running many applications, tearing is a bit visible on 480p full screen video. I'm not sure if this is normal. Could it be also the cause of black window bug?

Finally the black window bug, the bug appears when I have dozens of applications running. (firefox, thunderbird, amarok with album cover fullscreen, digikam with digikam editor both fullscreen, konversation, terminal fullscreen, kate, krita fullscreen, k3b and google earth fullscreen)
Normally, you dont run so many apps all at once, but on my usual workflow, I have firefox with dozen of tabs(not sure if tabs consume vram...), vmware server running 2 guest os, 2 pdf documents with kdpf, amarok, konversation, terminal, kate and maybe konqueror. the bug sometimes would appear (the only way to continue my work would be switching back to kwin window manager)

I'm sure that nvidia + beryl is the one that cause the black window bug.
aiglx does not reproduce the bug (but the framerate is just...)
I'm not really sure about no cow, xgl binding and indirect rendering. I can only remember that two or at least one of them do not cause the bug.

that's all. Nvidia sucks (better than ati though...). My laptop with intel graphic runs beryl without any issue...
Back to my Mac Pro with an ATI card, expose is just like scale in beryl. Can't wait for leopard to come out it has the 'wall' plugin in beryl
