Bug Description
Using Ubuntu 14.04, Compiz seems to apply a blur effect on the whole screen. Fresh updated display areas get transitional blurrier.
Behavior applies to the Unity Desktop and all desktop apps like Chrome, the Terminal, Steam Client but not on OpenGL games or Flash content and affects window borders, texts, images and all UI elements except the mouse cursor. -> see attachment
Nvidia proprietary drivers are in use.

It affects an essential hardware component (disk controller, built-in networking, video card, keyboard, mouse).

What happens if you turn off NVIDIA proprietary drivers?

Nouveau still seems no to support the GTS 250M and only runs in a 640sh resolution and every thing seems to be software rendered. I can't clearly state if the blur effect still applies due to the over all low resolution, but I think the described problem isn't applying in this case.
Furthermore the problem comes in sporadically under the proprietary drivers. I couldn't find the trigger for the wrong display behavior.

I had to switch to the 304.117 drivers to get rid of the problem. Seems to be related to the 331.38 drivers from NVIDIA.
With 304.117 drivers my gt650M does not work. Black screen. In safegraphics mode same.

I have exactly the same problem. GTX570, 331.38, Ubuntu 14.04
It may helps: before, when I used 12.10 lts I saw a few times this bug when I have done something to compiz(I don't remeber what exacly, maybe kill or run some effect)

It depends of configuration files because on guest session everything seems to be okay.
Marvin Janosch (janosch.koeln) wrote : | #10 |
Can confirm, other sessions like the guest session aren't affected.

There is a problem. Before, to repair this, I've created new user. But this morning the problem affected me again. Now, only my desktop and my all windows are blurred. The unity dash seems to be okay. Yesterday everything was okay, so please tell me how I can get useful log information for you.
Andrzej Golonka (wiecznywem) wrote : | #12 |
Okay, I figured out the reason.
When in the "nvidia-settings" in antialiasing settings, the field "Enable FXAA" is enabled, the problem affects. If I turned it off, everything will be okay.
To see every change I need to restart computer.
Marvin Janosch (janosch.koeln) wrote : | #13 |
Thought on something like that but seem to missed that one.
Disabling FXAA in the Nvidia driver fixes the problem (thanks Andrzej) but still, we know now Nvidia's FXAA is buggy.

Can confirm that turning Anti-Aliasing off fixes the problem, thanks Andrzej!
If I can be of help by by giving some log information, please let me now!
Status changed to 'Confirmed' because the bug affects multiple users.
