I have Opera 78.0.4093.184 on windows 10 pro (21H1, build 19043.1165). I'm not sure when it changed or if it ever had it, but the aero preview with context clicking to move/size/restore/minimize/maximize/close is missing. I over on the task bar icon, move the mouse to the preview window, right-click and it just closes. I get stuck when I switch my second monitor to another pc and the opera browser window can't be moved.

is this a known behavior? Has it always been like this?
