[nv/gfgo6200] random display corruption

[Robin Haswell]

I'm experiencing frequent display corruption on this Sony Vaio S3XP laptop,
which has an (unrecognised by lspci) Nvidia GeForce Go 6200 graphics chipset.
Types of corruption include gargbled pallette on X startup, blocks of windows
turning to "white noise", happens mostly with firefox but leaks into other
windows. Other small errors include dots beeing left all over a GIMP canvas when
the mouse is moved over it.

The corruption happens at random times (except for the GIMP canvas, which is
permanent), and can be solved with ctr+alt-backspace to kill the X server, which
is then reloaded by GDM. The display corruption almost always results in the X
server needing to be restarted within a short space of time.

No system information is included with this report, however information will be
provided on request.

Thanks.

This happens consistently when visiting http://www.webmasterradio.fm/chat.php.

I have also uploaded some screenshots:

Have recently found that these problems can be fixed by switching to an
alternative VT and then back to tty7, although usually requires more than one
switch to fix the display.

i think some of markv's commits to HEAD might've fixed this; will ping you when
the driver has been updated.

Hi, just some additional info about the GIMP canvas / white dots bug:

1. I'm seeing the bug on my new laptop: laptop = Asus A6B00K (aka "A6K"); Ubuntu
installation = vanilla 5.10 AMD64; graphics card = (unrecognised by lspci)
Nvidia GeForce Go 6200.

2. The white dots occur when a tool with a circle round the tip of the mouse
pointer (eg, pencil, paintbrush, eraser, airbrush, clone, convolve, smudge,
dodge/burn) is moved over the canvas.

3. The dots disappear when the canvas is redrawn (eg, the window is rolled-up
then rolled-down). When part of the canvas is redrawn (ie, an expose event after
that part of the canvas was hidden behind another window), that part of the
canvas is clean.

4. If you take a screenshot, the white dots are visible in the image.

Is this bug still present in current Dapper?

Apparently not. Please reopen if you can reproduce this on a supported release.
