I have Dell Inspiron 6400 with Intel 945GM:
- Code: Select all
chris@lappy ~ $ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

Strangely, I'm getting what I can only describe as a video triangulation / tearing type issue as can be seen in attached screenshot:
To get this I simply have float mouse pointer over firefox bookmark on bookmark toolbar. However it is not consistent, so wont do it every time. Move mouse pointer away, i.e. to top of screen and all is good again. The corruption disappears leaving situation normal. What's even weirder is that this only appears to happen when I'm browsing certain websites.
android.modaco.com is one, gmail is another. Mint forums seem to be OK so far. However issue is inconsistent. Cannot always get issue to appear.
Fresh install of Mint 12 (was running Mint 11 previously with zero issues) and all updates installed.
Wondering if someone more knowing than I can cast eye over screenshot? Perhaps recognise what's going on here. (99.9% sure that this is not a hardware issue as once things settle down all is fine)
Have tried to search, but at a loss how to describe this issue!
