Incorrect desktop grid

SUMMARY
The Desktop Grid effect isn't able to correctly show the grid when using ultrawide resolution(2560x1080 in my case).


STEPS TO REPRODUCE
1. Create a  (2 by 2), (3 by 3) or (n by n) Virtual desktop grid.
2. Enter the shortcut to show the Desktop grid.

OBSERVED RESULT
The left two Desktops are correctly shown, the right two desktops are incorrectly shown. The background is split up in two parts. Furthermore, the "control buttons" with which you can close a virtual desktop or create a new one are shown twice.


EXPECTED RESULT
All desktops are correctly shown and the "control buttons" are shown only once.

SOFTWARE/OS VERSIONS
OS: Manjaro KDE
KDE Plasma Version: 5.20.2
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1 

ADDITIONAL INFORMATION
UltraWide monitor 2560 * 1080
