I am using Freetube from Flathub, which uses Electron underneath. I force it to use Wayland, and when fullscreening a video, it immediately crashes. I got a coredump in systemctl Jun 26 00:07:35 PC systemd-coredump[391292]: [🡕] Process 391126 (freetube) of user 1001 dumped core.

Nothing in the backtrace suggests it's a KWin problem, but it's hard to tell since there are no debug symbols. Please either get a new backtrace with debug symbols (see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl) or else report this issue to the app developers. And frankly they're gonna want debug symbols too, so try your best to get those!
