Bug ID: 472509

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:

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
