Public bug reported: Binary package hint: xserver-xorg-video-nouveau
Certain graphical operations with the nouveau driver cause the display to lock up for several seconds. In particular, what looks like compositing operations. The most easily reproducible form for me seems to be with Chromium's tabs. When you try and drag a tab out to a new window it should show a preview of the tab. Very soon after the tab is removed from the tab bar the display will lock up for about 6 seconds before the translucent tab image will appear. It will then take about another 6 seconds before the the display will function normally. After this there seems to be no performance issue - it's just when first showing the tab preview. The mouse cursor is still able to move during this time. I believe that this might also happen when using the translucent on- screen volume control that appears when you use a keyboard volume control. After the first time this occurs, the volume control functions normally. Alt+Tab will cause the display to lock up for ~1-2 seconds before the tab-window previews appear.
