I noticed my memory was being maxed out and reaching into swap while playing games using wine, such as Overwatch. It seems the main culprit is plasmashell, which climbs to anywhere between 4 and 6GB and then stays there, even after I quit my game. I haven't installed any new widgets, and the system monitor tree view doesn't seem to be providing much insight. Is there any way I can diagnose this further and maybe file a bug report?

I'm running OpenSUSE TW KDE 5.26.4 Xorg with a 5700XT
