Corrupt display in moovida

[Onkar Shinde]

Binary package hint: moovida

When I launch moovida, I see no icons in the home screens. Also the menu headers seem to be garbled. Please find attached a screenshot showing the problem.

Extract from the chat with developers:

(07:29:11 IST) oSoMoN: it would also be interesting to see if pigment examples run fine on your setup
(07:30:57 IST) oSoMoN: try e.g. /usr/share/doc/python-pgm/examples/image.py

Can confirm strange display. Running on 64 bit Karmic, compiz enabled, nvidia 185.18.36-0ubuntu3.

[Onkar Shinde (onkarshinde)]

I have added few more screenshots showing strange display problems.

The example /usr/share/doc/python-pgm/examples/image.py works for me but moovida shows these problems.

@Mark: your problem is different than Onkar's.
Can you please file a separate bug report?

[Loïc Molinari (loic.molinari)]

@Mark: This is unrelated. I guess you've plugged two displays on your PC, this is currently not supported.

@Onkar: Can you please attach the output of the "glxinfo -l" command? From my experience, I'd say that it's a graphics driver bug. It would be interesting to test other applications using the 3D graphics acceleration through OpenGL (neverball, tuxracer, google earth, etc) to see if the rendering is correct.

[Onkar Shinde (onkarshinde)]

This indeed looks like driver bug. As I am also observing another similar bug identified as driver bug - bug #429295

[Onkar Shinde (onkarshinde)]

This is indeed a video driver problem. Surprisingly the problem is fixed with radeon.modeset=1 kernel parameter. But the moovida becomes very slow.

Hi onkarshinde,

Thanks for including an image to demonstrate the issue. Could you also please attach the output of `lspci -vvnn` and `dmesg`, and attach your /var/log/Xorg.0.log or Xorg.0.log.old file from after reproducing this issue. If you've using a custom /etc/X11/xorg.conf please attach that as well.

[Onkar Shinde (onkarshinde)]

I am not using any xorg.conf at all.

In Lucid we're shipping modeset=1 as the default. It's true there are some performance regressions (see lp #544496)
