If you need more information, please tell me. Don't know what's useful.

STEPS TO REPRODUCE
1. Have two monitors
2. Maximize KDE on second monitor

OBSERVED RESULT

EXPECTED RESULT
Normal rendering.


SOFTWARE/OS VERSIONS
Arch Linux

ADDITIONAL INFORMATION
Using kmail2 5.12.80 beta1 (19.11.80)

I manually set up the monitors with

This bug affect also Lokalize and VirtualBox at least.

The bug is not directly related to KMail

When I plug a screen to my laptop, the laptop or external screen is affected and windows work well on other screen. The only affected screen is the virtually (right one).

If I plug 2 screens on my laptop problem occurs on the 3 screen


However I tried to reproduce it with LXQt and KWin as window manager and it works fine.
