Description of problem: kpat uses a lot of memory, until it starts to use swap. You have to kill it to get control of KDE again. Version-Release number of selected component (if applicable): kpat-18.12.2-1.fc29.x86_64 How reproducible: Not systematic, but very often. Actual results: kpat and KDE becomes very, very slow, unusable Expected results: Additional info:
I'm seeing similar slow downs with kpat. It will often die or stop responding needing a force kill to exit. I have kpat version 3.6 on f29. Not sure if this will help, but top reports the following when kpat is first started VIRT=863295 RES=97984 SHR=64964 Whiching to another game can cause the memory requirements to jump VIRT=1098908 RES=349600 SHR=66588 Memory needs increase as you continue to play although they may decrease at times. VIRT=1104736 RES=355192 SHR66588
It is unusable, Tried kpat-18.12.2-1.fc29.x86_64 and 18.12.3 from rawhide
kpat-18.12.2-1.fc29.x86_64 on Fedora 29 is very slow/hangs and starts to consume 100% cpu. According to other forums the problem disappears if "Solver" is disabled. After downgrading to kpat-18.04.3-1.fc29.x86_64 everything works as expected and cpu usage is negligible.
Ideally, please report this upstream to bugs.kde.org We (downstream) have limited resources to debug/fix this ourselves, at least not with upstream collaboration.
