SUMMARY
***
Reopening an alt-tabbed Apex Legends game can crash kwin_wayland. Previously when I did this, the game itself crashed and it froze the desktop for a couple of seconds but after setting PROTON_LOG=1 the game took kwin_wayland with it. It takes quite a while, a couple of games and many alt-tabs to repro this. The most opportune time to alt-tab seems to be in the pick screen and then connecting back when the dropship is in view.
Backtrace seems to point here: https://invent.kde.org/plasma/kwin/-/blob/v5.27.6/src/libkwineffects/kwinanimationeffect.cpp#L735

STEPS TO REPRODUCE
1. Set PROTON_LOG=1 in steam for Apex Legends
2. Play the game, occasionally alt-tabbing to the desktop

OBSERVED RESULT
Crash after about 5 games played
