freecell on kpat showing glitches

SUMMARY

There are many small lines randomly appearing across playing area. You can say that it looks like a broken signal cable.
If I switch focus to any other application they are temporarily gone. After a move or two, lines appear again.

STEPS TO REPRODUCE
1. Set Scale to 125% in System Settings > Display & Monitor
2. Open kpat
3. Start any game

OBSERVED RESULT
There are many black and white lines

EXPECTED RESULT
no glitch
