And another update: I have occasionally fixed that by reenabling desktop icons.
I have previously used Ubuntu Tweak to disable icons on desktop. Apparently this removes some kind of root nautilus window (which also draws the background BTW). It looks like Compiz expects this window to exist, and if it does not exist and all other windows are minimized then Compiz goes crazy. To fix the missing desktop background I have reset this option to the original state, now Nautilus draws background and icons, and I can safely minimize all windows. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1032276 Title: [nvidia] Graphics freeze when I close or minimize a window Status in Compiz: Confirmed Status in compiz package in Ubuntu: Confirmed Bug description: Often when I minimize or close the last open window so the desktop becomes visible the graphics freeze for several seconds up to 2 minutes.
