--- Comment #21 from Sebastian Turzański <dpba...@wp.pl> --- That was a good hint, i now it was cause by somehow hanging AnyDesk application, Some months ago I was reporting that the tray icon of Anydesk was showing on top left corner even if the tray was completely else - this has been solved but it seams it was solved in a way that sometimes some 'leftovers' from anyDesk are still covering the left top screen corner. I connected the dots when the same on-hover message appeared when I hovered of anydesk TrayIcon - and when i right clicked in that case there was no option to see proper AnyDesk's right click menu which shoudl contain 2 items : New Session, Quit Instead I was getting a context menu simillar to the one You get in taskbar icon. I killed anydesk and restarted it and everything works ok. I will try to observe more but i'm sure that anyDesk users can confirm it.
