Hi, indeed this is a bug that still needs to be solved, but this issue is not a year old yet 'only' 5 weeks.
Just checked it again and thought it was solved, but that was because I was working on my normal laptop screen. Only on the connected external monitor (either as only monitor as extended desktop's main monitor) does this problem occur. I dont know about you Pikalax whether you have it on your PC's/laptop's normal monitor or also on an external monitor...It's not a laptop/
driver problem because colleagues of mine have it as well on completely different machines and monitors.
So, Microsoft, please still solve this.
The workaround i'm using in the meanwhile is: make the taskbar two rows high instead of the normal one row high and the problem does not occur anymore.
