--- Comment #1 from Thomas Lübking <thomas.luebk...@gmail.com> --- Afaiu kwin and openbox do act pretty similar - a minimized dialog is added (but I assume that's not what unreal wanted to achieve) My guess is that the client reversed the desired transiency and the (fullscreen) game window is transient for its dialog, so whenever you try to activate the dialog, you get the game window (which is likely uninitialized, explaining "screen gets unresponsive. Alt+Tab works") active instead (and it's also always on top of the dialog) Can you switch to the other VT and dump "xprop" and "xwininfo" on game window and dialog? Both take an "-id" parameter and "xwininfo -root -tree" will print a list of all windows. Don't forget to "export DISPLAY=:0" -- You are receiving this mail because: You are watching all bug changes.
