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)

    Debian doesn’t have package groups in that sense. kde-full is just a package which depends on the other KDE packages.
    So, if you tell it to install kde-full, it’ll just check that, yes, it does have the kde-full package installed, whether all the dependencies are fulfilled or not.

    You can try doing apt --fix-broken install (without specifying a package), maybe that will pull in the missing dependency.
    Or you can reinstall: apt reinstall kde-full

      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.
