SUMMARY
In the newer version of kpat (starting with Kubuntu 19.04), solver is much slower, hogs CPU, and logs a_lot to .xsession-errors (as much as 500K per second)
STEPS TO REPRODUCE
1. Start kpat.
2. Start a monitor for CPU and ~/.xsession-errors
3. Start a new game that stress the solver, like Mod3 or Spider
OBSERVED RESULT
Observe the too much logging, CPU hogging, and slow solver
EXPECTED RESULT
Solver should not log (so much?) calculations to ~/.xsession-errors (for non-debug?). Solver should be faster (like in older versions of Kubuntu) and not spend so much time Calculating...

Linux/KDE Plasma: Kubuntu 19.04
(available in About System)

ADDITIONAL INFORMATION

Bug doesn't happen in Freecell and maybe some other games, so probably is different than these two bugs: https:/ /bugs.kde. org/show_ bug.cgi? id=405187 and https:/ /bugs.kde. org/show_ bug.cgi? id=406094
