Noticed this bug yesterday when recording my screen with obs studio on Wayland session of neon unstable.

Comment 2 Nate Graham 2022-01-20 23:30:32 UTC

Cannot reproduce the issue with current git master; the cursor shows up for me.

Regardless, this is either a KWin issue or an OBS issue; moving to KWin to start with.

Cannot reproduce too, works fine in git master.

Comment 4 Behzad A 2022-02-06 13:09:47 UTC

Currently, I'm using git master (openSUSE KDE:Unstable(Krypton) repo) and cannot reproduce the issue anymore

Right, there were some cursor fixes in screencast plugin, they might've fixed this bug too
