Severe graphical bugs with r300 based ATI gpus

Hello

I have a thinkpad r60 with a radeon x1300, and a iMac 5,1 with a radeon x1600. Both are based on the ATI RV515 core, which uses the mesa r300 driver for 3d stuff. When running hardware accelerated applications like chromium (which still supports hardware acceleration on opengl 2.1 based hardware) there are severe graphical bugs on both machines. This is defenitly not a hardware issue because no issues were there when both machines had their original OS (windows xp for the r60, and macos for the mac).

The iMac is running gnome wayland session, and the r60 is running xfce in X11. Both have very similar graphical bugs. The graphical bugs seem to also spread outside the application which is hardware accelerated, the font in the terminal for example stats to look corrupted after a while. I have not tested much 3d software, but stuff like glxgears and old minecraft do not cause such graphical bugs.

Here is a glxinfo output on the r60 with the x1300

Here are some example images of the graphical bugs: https://imgur.com/a/mesa-r300-corruption-ciQ8aW2

Please ask if you need any more logs or something like that, I have no idea where to even start looking other than like dmesg, which didn't seem to have anything interesting.

Try with a simple Window Manager for X without a compositor like openbox or twm.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: Severe graphical bugs with r300 based ATI gpus

I am using xfce with the compositor disabled, so I guess that should be equivalent to running something like openbox. However Ill try some different ones anyway.
