Changes introduced some time ago cause some parts of the display not to update anymore. Example: In file manager, icons do not appear, or icons from previous folder stay on the screen until mouse over etc. Example: When terminal blinks (visual alarm), terminal stays white instead of going back to black until user action. Example: In terminal, cursor is visible on every character it moved over, that is, going over text with left or right keys will leave bits of the cursor on the screen. I cannot capture this using screenshots, the problem will not be visible there.

Sorry, I should also have mentioned that I'm using compiz when this happens.
This might be a framebuffer compression issue. Does putting the following in your device section in xorg.conf help? Option "FramebufferCompression" "false"
(In reply to comment #2) > This might be a framebuffer compression issue. Does putting the following in > your device section in xorg.conf help? > > Option "FramebufferCompression" "false" No, it does not. Here are the other xorg.conf settings: Section "Device" Identifier "Intel" Driver "intel" # Features Option "XvMC" "true" Option "XvMCSurfaces" "6" # Tweaks Option "AccelMethod" "UXA" Option "PageFlip" "true" Option "TripleBuffer" "true" Option "XAANoOffscreenPixmaps" "true" Option "BackingStore" "true" #Option "FrameBufferCompression" "true" Option "MigrationHeuristic" "greedy" #Option "Tiling" "false" #Option "ExaNoComposite" "false" EndSection
