Hi,
since I yesterday upgraded 2 TW installs with KDE to latest TW snapshots, both
20210212 as well as 20210215, and since then Skype (latest version from its
own repo) seems to be running in background well, i.e. it notifies me about
new message and so on, but the window doesn't render at all, it contains
basically background, so it's not usable at all. I wonder if this could be
related to possible sandboxing issue mentioned by Dominique at Tuesday, but I
have 64bit systems, and I have libqt5-qtwebengine 5.15.2-6.1 from tw-update.
Any idea what could be wrong?

It renders and works fine for me. Maybe you can try to disable KDE's compositor to see what happens...
