When I maximize some of the windows all decorations disappear (by all, I mean on all windows)... Is that common issue on Unity or I'm just unlucky to have some prone to that bug configuration? Anyone have idea how to fix this?
It won't fix after unmaximize. It seems like maximazing window simply crashes window decorator. Decoration isn't displayed for all existing windows and any new ones. Only way I found to fix this is to run
compiz --replace (but this ruins current windows placement - all windows end up on same desktop).
It happens almost every time I maximize window.
