Hi everyone, I ran apt full-upgrade last month and accidentally deleted a couple packages that weren’t supposed to be removed, due to me not paying enough attention. I could recover most of the system just fine, since most of the missing features and related packages were obvious to me. However, I still couldn’t figure out why transparency is not working on KDE, both in Wayland and X. I suspected it could be a missing compositor, but libwayland and libqt6waylandcompositor6 (and related packages) are all installed (and that wouldn’t explain why it isn’t also working on X).
I have attached a screenshot to illustrate what I mean.
I would appreciate if anyone could help me figure out what package might be missing that is causing this issue. Thanks in advance!
EDIT: Thank you so much everyone! I finally solved my problem. I just had to replace libqt5quick5-gles by libqt5quick5 (non gles version).
Commandline: apt install libqt5quick5
Install: libqt5quick5:amd64 (5.15.10+dfsg-2+b2)
Remove: libqt5quick5-gles:amd64 (5.15.10+dfsg-2+b2)
Thanks for the tip! However, I tried apt reinstall kde-full and apt --fix-broken install, but no packages were installed and (unsurprisingly) the problem still persists.
Hmm, then I’m guessing, it’s not a missing package. It kind of doesn’t quite make sense anyways, as KDE Wayland can’t be run without a compositor.
Maybe the installed Breeze theme is broken. If you install a different Plasma theme in the System Settings, does that give you transparency?
I agree with that. I suspect you might be right. SDDM (Breeze) is also weird with transparency. However, I just installed materia-kde but unfortunately the problem persisted (screenshot attached). Before that, I ran apt purge kde* plasma* libkf* and apt install kde-full. That too didn’t solve my problem.
I can’t believe, I seem to be the first to ask this, but are maybe graphics drivers broken? Are you on Nvidia?
Those black squares for the status bar icons, I think, I’ve seen before somewhere, so I’m at least guessing that your problem isn’t a completely new problem…
