Hi Netlama,

Thanks for the heads up. Do you have any idea when the black window bug will be fixed? Apparently this is non trivial to fix? Will it be fixed in the next release?

Would also appreciate this bug being fixed ... was very disappointed to have problems with my brand new nvidia card ...

Please, is there any estimated fix date on the black window bug? Or, is it even considered a high priority by the devs at nVidia?

Thanks.

And what is expected to address my friend?!
Browsing the forum I found all the existing issues in the previous drivers included in the new one!! How much more will we have to wait for a SOLVED bug like <trail garbage in nvidia settings> or this major bug that is common for all NVIDIA users for so long to be addressed in a new driver?

Seems to be pretty much only "support" for a few newer cards

Not that it's bad that those new cards get some support, but having the black window bug around for so long is pretty much ridiculous.

I could be really off...but I have a theory regarding this whole "black bug" mess.

We all know it is because Vram is running dry on our systems using indirect rendering. Its a very ungraceful effect for a problem that is easy to conceive.

I think XGL avoids this problem because it is an independent process that uses system RAM in many cases instead. Windows XP does not have this problem because the only things really using Vram are programs, and anyone that has played a game past when the VRAM ran out knows what happens in many cases (my favorite way to crash Unreal Tournament).

It is in Vista that I have noticed interesting results. In Vista my 6600 GT 128mb is reported to have three times that much (if not more) meaning that in Vista my non-Turbocache (never could be- AGP) is acting like it has Nvidia's most unappreciated feature. It must be sharing ram with the OS when it goes past the line, as I can open a hundred windows and non will be full of blackness. Everything about Vista makes it seem like its Aero interface is more like XGL than anything else we have (just a much more complete, Directx based flexible version). So it can cheat the system the same way XGL can. The same and only way any solution can- using the system RAM.

So for Nvidia to fix this problem in XGLess Xorg would require backporting Turbocache to cards (and system boards) that were never designed to have it. Might be near impossible.

With this realization I came up with my own fix- get a card with more VRAM or that supports Turbocache in hardware. There are 512 7300 GT cards out there for cheap (heck, even 256 6200s) that would fix the problem. I settled for a 7600 GS 256 mb that could fit in a low profile case. It drives two monitors well and I have not experienced the black bug yet (I have not looked for it though). I know that this is the worst possible solution to the problem- Throw out good hardware!- but it worked for me. Ebay is a great place to find cards no gamer would want (low end cards with lots of VRAM) for cheap....

The bug still affects those cards. True, you might get many more open windows before the black windows bug shows up, but it's still there.

Question Re: beryl black windows bug

Can anyone explain me why when you use ''force AIGLX" the bug does not appear?
And what's the difference between "Strict Binding" and "XGL Binding"?
Cause the force AIGLX works good only with XGL binding as I have mentioned in my previous posts...

OK Listen to me all...
The setup workaround I found "Texture from Pixmap" "force AIGLX" "XGL Binding" does NOT WORK with 100.14.03 driver!!!!!

I just tested it and it's Unbelievable!!!

Meaning that the new driver does not have even this workaround solution for me!!!
I am downgrading to 9755 immediately...
Not only the new driver does not address the problem as very clearly all NVIDIA'S people said but also it doesn't give me and the only way to handle acceptably the bug!!!

Lightbulb Re: beryl black windows bug

A user on another forum suggested Rendering Path to Copy: evidently the buggy function which causes the memory leak/black windows isn't used with this option selected. It seems to work so far, but I'll repost with my long-term results anyway.

[Edit]
It also seems that nVidia and the Blur effect plugin don't get along, so try disabling that as well.

Telling it to 'use copy' makes beryl slow as molasses. That is not a viable option.

I see some but not much difference in Beryl between Auto and Copy with all other settings being Auto. I ran glxgears on Kubuntu 7.04 x86-64 against both configurations:

Code:
Render Path = Auto
bob@soli-deo-gloria:~$ glxgears -info
GL_RENDERER   = GeForce 8800 GTS/PCI/SSE2
GL_VERSION    = 2.1.0 NVIDIA 97.55
GL_VENDOR     = NVIDIA Corporation
...lots of stuff...
78376 frames in 5.0 seconds = 15675.043 FPS
79176 frames in 5.0 seconds = 15835.151 FPS
79202 frames in 5.0 seconds = 15840.243 FPS
79183 frames in 5.0 seconds = 15836.514 FPS
79244 frames in 5.0 seconds = 15848.363 FPS
79198 frames in 5.0 seconds = 15839.470 FPS
79135 frames in 5.0 seconds = 15826.955 FPS
79155 frames in 5.0 seconds = 15830.991 FPS

Render Path = Copy
bob@soli-deo-gloria:~$ glxgears -info
GL_RENDERER   = GeForce 8800 GTS/PCI/SSE2
GL_VERSION    = 2.1.0 NVIDIA 97.55
GL_VENDOR     = NVIDIA Corporation
...lots of stuff...
75273 frames in 5.0 seconds = 15054.446 FPS
75325 frames in 5.0 seconds = 15064.871 FPS
75295 frames in 5.0 seconds = 15058.578 FPS
75343 frames in 5.0 seconds = 15068.540 FPS
75333 frames in 5.0 seconds = 15065.889 FPS
75297 frames in 5.0 seconds = 15058.769 FPS
75352 frames in 5.0 seconds = 15070.268 FPS
The drop in FPS is about 5% with Copy on the 8800GTS. Of course, glxgears probably isn't using TFP much for the test and, as we all know, isn't a benchmark. Visually, though, I cannot discern a significant difference. I'm sure the relative loss will vary somewhat by card and their individual drivers.
