Hi, after long time I need help again :) I have this problem: Sometimes (like once a week, sometimes more often) when I click on the Show desktop icon many new “windows” jumps on. They can not be maximalized I can see just the part of the top panel of them… I made a screenshot of this issue is it possible to upload it somewhere here?
I have never seen anything like this before (Can understand why you wanted to upload a screenshot). Looks like all Windows have been minimized and tiled, but at the same time forced to be shown on the desktop.
My guess would be some desktop management application (multiple desktop thing, graphics driver utility or similar) that is interfering with Windows.
If you cannot identify such an application then I would start the new year with a fresh install of Windows.
