Default 295.33 or flash bug?

I was playing a youtube video, then attempted to maximize the window and everything semeed to freeze. I could after a while ctrl+alt+f1 to kill the processes and recover my X session. Nothing dmesg, but xorg contains some stuff (see attached).
Intel Atom / Ion gen1, Archlinux 64-bit. flashplugin-11.2.202.228-1

Note the attached nvidia bug report is from after a system reboot, but it contains the system information, so.

Default Re: 295.33 or flash bug?

It's a bug in X.org server which is triggered by Adobe Flash.

In this version of Flash Player Adobe developer enabled Accelerated Video Rendering via OpenGL, but it doesn't play nicely with X.org server and NVIDIA drivers.

There must be a way to disable Accelerated Video Rendering, or we'll have to restart X.org server once in a while. Unfortunately nor X.org developers, nor NVIDIA want to solve it.

As a workaround you can downgrade to one of previous Adoble Flash Player releases (however bare in mind that they have known vulnerabilities).

And this problem also manifests itself in video leaking through black parts of other windows.

In short Adobe Flash Player 11.2 is utterly unusable for NVIDIA users.

Okay, thank you. I'll downgrade flash (vulnerabilities, pfft! ) and see if that improves.

Do you have a source for this?

A source for what?

Also this Flash player has this terrible bug which a lot of people experience: White people are turned into smurfs on youtube

It has over 4 duplicates, but Adobe cannot or more likely doesn't want to reproduce it.

Well, until this bug is fixed, and if your card support it, you can switch to nouveau driver.

It is what I have done.

I downgraded flash for now, things seem to have improved. Nouveau doesn't support VDPAU unfortunately, so it's not usable.

It's not an option for too many of us as nouveau doesn't currently support power management, i.e. you end up with a GPU fan at 100% of its speed with either the lowest or the highest power level (and both are undesirable).

"Smurfs" problem only happens if you use hardware rendering with software decoding. So you have two options:
- enable vdpau (and bear in mind that youtube is the only website which does not crash left and right)
- disable hardware rendering altogether.

Don't count on it ever being fixed by Adobe. The final version of Flash 11.2 was released and it is the last version that Adobe will be releasing for linux. From now on you have to depend on the Google Chrome implementation.

For linux, the flash plugin is dead.

I thought they said they'd still provide some level of bug and security fixes for 11.2 for a couple of years. Just no v11.3 or v12. Either way, it's time to start phasing out flash...
