Default 177.68 graphical glitches

Upgraded to 177.68 today, and it started making big square chunks of text in firefox/konsole just disappear. rolling up the window or min/max it would usually fix it, not always. Starts acting up immediately on boot and reproducible every time. Nothing would crash.

Here is the bug report, it is after rolling back to 177.67, testing and the bug disappeared.

Are you using InitialPixmapPlacement=x?

I experienced the same with my 7600gt upgrading to 177.68. But it seems the text gets drawn normally again if i disable all recommended performance tweaks.

I am seeing the same thing. I wonder why the tweaks have suddenly stopped working.

The only option that creates trouble is the "PixmapCacheSize". Any value in there leads to the corruption of the display. And this was the option which was supposed to improve the window re-sizing slowness. We can't a break with nvidia drivers....:-(

Is the corruption you're seeing similar to what was reported in this thread?
If so, the next release from the 177 driver series should feature a fix for this issue.

yes. Another 6600GT here. The scale of corruption (text disappearing or blocks and then reappearing when you switch to another window) is huge with pixel cache set to any value.

In my case, reverting all tweaks doesn't make the corruption go away completely. It still appears in konqueror on a small scale like part of a line is gone in konqueror. Reverting back to 177.67 is the only solution.

Since, this is a major breakage, I was wondering if nvidia wants to do a quick release with just the fix for this problem. 177.68 is unusable and complete waste of time otherwise.
