Bug Description

OpenGL rendered textures and text are often striped. E.g panel shadow, unity dialog's bottom border, separators in panel, text in Extreme Tux Racer.
Example image shows the faulty panel shadow.

The bug has existed since the start of 11.04 (and was also present in 10.10 with extreme tux racer).

lspci -v | grep VGA
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon Xpress 1250 (prog-if 00 [VGA controller])

Seems to be an 3D rendering problem of the radeon driver since it affects Mint(Debian Edition as well as Ubuntu based) Cinnamon too.

I can confirm the bug in:
- Fedora 16 Live CD
- Ubuntu 12.04 (or every edition with gnome-shell)
- Linux Mint (with Cinnamon)

Note:
Everything is fine in Gnome2 (in Ubuntu), and MATE (in Mint) except some time in watching Youtube video (or other videos) appears flicker horizonal lines in the monitor in random position!

Mattia,

This bug is about Unity. If you're using Gnome Shell then please log a new bug.

Still exists in Ubuntu 13.04.

Attaching a screenshot (looks even worse than in 12.10)

I have no problem since 12.04 (to 13.04), do you?

Madis (madisliias) wrote :

It seems like the bug seems to be quite ATI Radeon Xpress 1250 specific.

Here's also a duplicate with some more useful discussion:

Had this bug on Unity a long while ago. Now have this bug whilst trying out Cinnamon on Mint 15.

I have ATI Radeon Xpress 1250

Madis, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.

I don't have my old laptop anymore, so can't test it.

There is some discussion here, though (but might not be exactly the same problem):

Is it possible to reopen this bug, i have the same issue on somsung P500 with Radeon Xpress 1250?

Peter, it will help immensely if you filed a new report via a terminal:
ubuntu-bug xorg

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.
