[PM800]S3 Unichrome Pro IGP - Random graphic corruptions

[thewk]

I currently have Fujitsu Siemens AMILO L7300 Laptop and it has Via/S3 Unichrome integrated GPU. Openchrome driver is installed and glxgears is working.

The problem is random graphic glitches, which means that all of sudden menu buttons and text will disappear, they can be redrawn if I move a window over them or click where the button should be, best way is to maximize application to fill the whole screen, video player like Kaffeine for example, and then minize, buttons and text is then redrawn. Couple times whole system has locked up and I believe the reason is related to graphics / graphics driver.

Does this problem exist in VESA driver?

[thewk (theewk)]

Those corruptions are usually like in Kaffeine in that pic, text or images in buttons not showing, only edges.

Check if this error exists with vesa driver.
To do this go to
     Section "Device"
and change
     Driver "openchrome"
to
     Driver "vesa"

or just add line:
   Driver "vesa"

Could you test if this bug exist in the latest openchrome revision.

Did you test if this bug exists also in "vesa" driver ?

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
