Thanks for contacting us. Do you see this happening with non-Blazor app - just MAUI?

@mkArtakMSFT I just made a brand new Maui app, non-blazor, and it does it as well. I even tried the projects on another computer and get the same result.

@Redth Is this a known issue?

I have not seen this before. Is this on a machine with the monitor connected or via some RDP/remote/streaming display?

Can you reproduce this on other machines or with a plain WinUI 3 app?

@mattleibow This is on just my regular everyday computer. I've made sure no background apps or anything are running that could affect it. I also tried it on my second machine and it happened there too, however it did seem to not happen on my work computer in the office. I just don't know what the issue could be. I could try reinstalling all of visual studios potentially?

I have not tried a plain WinUI 3 app but I will try that today.
