Icons and fonts break after external monitor connection

Hello there. I am using Manjaro (Kernel Version 6.1.11-1) with KDE Plasma (5.26.5) on Asus G513QY. I also have Windows 11 on that laptop.

When I connect external monitor via usb-C port and restart session all my icons and task manager bar disappear and the system becomes very laggy. When I disconnect external monitor and restart all gets back to normal.

I tried to fix this issue same way as in post named All desktop and menu icons missing (sorry I can’t post links yet) but it didn’t help.

Can someone please help me to solve this issue.
