Created attachment 1607979 [details] Display corruption I am experiencing display corruption when trying to run compiz on my Ryzen 7 2700U laptop with integrated graphics. Everything works fine with macro (MATE's default window manager). Compiz also works fine on the same machine if I boot into the Fedora 30 MATE-Compiz live image. My current system was installed with the Fedora Server spin and MATE was later installed with groupinstall "MATE Desktop". I don't know how to troubleshoot this further. I have tried running: compiz --replace compiz-manager fusion-io All will load up compiz but with display corruption. See attached image. I can confirm that compiz is running and "works" (such as wobbly windows) but it's unusable due to the artifacts. This appears to be a software issue.
After referencing this bug: https://bugs.freedesktop.org/show_bug.cgi?id=111122 I was able to find a solution by adding "export AMD_DEBUG=nodcc" to the global profile. I've attached a file "amd_fix.sh" which if placed in /etc/profile.d/ will provide a workaround.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

This bug still exists in Fedora 32. Don't know how to reopen this issue on bugzilla 5. Also, I don't know if it's related to compiz, because when Fedora 30 released, compiz still works at that time, the version of compiz are same.
