There are too many bugs for me to manage and they mostly seem to be around the same problem(s).
The COPR build seems to have fixed most of the issues related to Wayland but removing GLX from the Coin build. As I don't maintain Coin3 I am not planning on doing the same in Fedora 30/31, but as my original assumption that the problem was linking with Coin4 while Pivy was linking with Coin3 was not correct I just completed updated builds for 30/31 with the same fix as in my COPR.
If you have new information specific to your bug you can respond in the original BZ but general stuff can be put here instead so everyone sees it.
Ok, new builds are pushed. Please temporarily disable the COPR if you're using it and do a "dnf --refresh distro-sync" to make sure all the COPR packages are removed and then try the update and report here or to your original bug.
