[gentoo-user] ati-drivers text corruption problem.

[Grant Edwards]

All of the recent ati-drivers seem to have a bug that corrupts
contents of some scrolling text windows.  It looks like this:

  http://www.visi.com/~grante/fglrxbug.png

Has anybody else seen this issue or know what to do about it?

  
Older versions of the driver that didn't have that bug won't
build for recent kernels and/or run under xorg 7.2.

The Xorg "radeon" driver doesn't have this problem, but DRI
support in that driver doesn't work for some of the programs I
run.

wow, never seen that and I've used most versions of ati-drivers up to
x11-drivers/ati-drivers-8.37.6-r1

maybe provide your card specs?

unfortunately, neither the xorg radeon driver nor the ati radeon driver
give me very good performance... on a RV350 "Mobility Radeon 9600 M10".

The only program it reliably happens with is aterm.  Other
terminal programs don't seem to trigger the bug.  I suspect
that rxvt will also trigger it since they share a lot of code.
I'm not sure when it started to happen.  I think it worked OK
back in the 8.2x series, but you can't run those drivers with
newer kernels and new versions of xorg.

It's an IBM Thinkpad with an M22 X300 chipset w/ 64MB of
RAM.  I can look up the chipset rev tomorrow.

Yea, I've noticed that.  The radeon driver DRI support only
works for some programs and at about a 20% reduced frame rate.
