Maybe related to this: > https://lkml.org/lkml/2019/12/14/263 > but that was kernel 5.4 not 5.3. I spent a bunch of time looking for in between kernels to try. In the process I tried also with RV250 and RV380 without being able to repro. Eventually I stumbled onto radeon.agpmode=-1, which worked around the corruption well enough on Fedora and Tumbleweed. I got luckier and found after reading your lkml URL https://bugs.mageia.org/show_bug.cgi?id=26237 reported against kernel-desktop-5.5.4-1.mga7-1-1.mga7 to produce corrupt Xorg video described much like observed here. That bug reports fixed with kernel-desktop-5.5.6-1.mga7. I found and installed 5.5.4 and confirm it's broken, and that it's fixed in 5.5.6-2.mga7, which explains why I failed to experience this in Mageia, where I had jumped from 5.3.13 to 5.4.17. Apparently whatever Mageia did should be upstreamed if it hasn't been lately. Fedora's 5.5.10 remains bad. -- Evolution as taught in public schools is religion, not science. Team OS/2 ** Reg.
