window appears white when resized at times on a secondary screen sometimes primary

Binary package hint: compiz

a lot of times happen were if i have a window on a secondary screen the window appears white but the borers appear alright.... also it seems sometimes when using print screen the window gets fixed but not all the time.....and some times compiz --replace fixes it but at times just makes it worse were you just cant see the window

screenshot.png shows what im talking about

seems to also make it were anything maximized while its happening gets the problem no matter the screen it's set to which for me causes a lot of problems when im useing one screen to hold info and another for using blender at full screen

my screen resolutions are set were the primary is 1280x800 and my secondary is set to 1920x1200
