Hello, yesterday I discovered something strange when i was watching youtube some strange white window appeared on my second monitor in left bottom corner, I tried to discover whats that but it ended alf+f4 and it dissapered. For a while I had issues with for example running some apps from my windows bar like some transparent window would block it. Same today it appeard on windows start on second monitor in the left bottom corner I can move it but i have no idea how to discover whats that, so i think that app or whatever it is was working for a while and the only way that I could find out that it is there in the background it was that moment that window went white and I could actually see it.
