Comment 0 for bug 1122478

A Steam Linux user reported this problem.

He created a video which shows a sequence of minimizes and maximizes. Initially the Steam client window does not have decoration. This is expected as Steam sets _MOTIF_WM_HINTS to disable decorations and never changes them again. As the mins and maxes are performed _MOTIF_WM_HINTS gets changed and decorations are enabled. Checking xprop confirms that the window properties actually are different. As far as I can tell the Steam client is not doing this, so it seems like Unity is?
