I also use the audacious media-player for music in its x11amp compatible skinned mode and that is has serious issues when used without QT_QPA_PLATFORM=xcb under GNOME3. I thought this was just a special case because of the skinned UI, but I now see that it is part of a wider pattern. I was going to write the following here: """ I can understand if the KDE SIG wants to use Wayland by default when running a KDE Wayland session, but under GNOME3 this indeed seems like a bad idea for now. Maybe instead the QT_QPA_PLATFORM environment option can be set in the KDE wayland session, so that Wayland is used there while leaving GNOME3 alone ? """ Which seems like a reasonable compromise to me, but then I looked at the patch from [2] and it seems that that is the upstream default and the Fedora packages are actually overriding this sensible upstream default. > I think this downstream patch should be dropped from Fedora. I tend to agree, it seems this downstream patch breaks at least 3 apps: 1. KeepassXC 2. calibre 3. audacious And I have a feeling it breaks all Qt apps to at least some extend, now the changes process page [3] does list a couple of reasons why this is necessary, but I just checked and calibre looks fine with the mutter provided window decorations for X11 windows instead of using CSD, so this does not seem like a strong argument. I can understand that it is desirable to make this change, but it seems that QT5 just is not completely ready for this yet. For me the patch[2] breaks 2/2 Qt apps which I regularly used, so it seems that it would be best to drop this downstream modification for now.
