graphics corruption with current drivers and 2.6.38-rc

graphics corruption with current drivers and 2.6.38-rc

Hi,

I noticed occasional graphics corruption in Xfce terminals. A
screenshot is attached.

This happens with kernel 2.6.38-rc (at least rc6 to rc8), Xserver
1.9.4, libdrm 2.4.23, xorg-intel 2.14 (the versions from Debian Sid
except for the kernel). 

The hardware is a Mac mini Core2 Duo using i945 graphics. Someone else
on IRC noticed this as well, using a G31 chipset and gnome-terminal. We
both have compositing enabled.

There are no log messages about this in the kernel or Xorg log.

Regards,
Tino

Hi Tino,

This looks like the rather newly introduced glyph corruption problem:

https://bugs.freedesktop.org/show_bug.cgi?id=34980

Unfortunately no cure known, yet.

Yours, Daniel

Thanks. I don't know if this is connected, but I enabled composite on
my ThinkPad X61s using i965 graphics and got corrupted images in the
web browser. I disabled compositing and everything is fine again.
