Hi: Upgraded to 7.5-2 (via 7.5-1) and things changed to slightly better as I can enable Composite extension again without suffering visible overlapping issues, but still not perfect as screenshots still show black if a 2D app overlaps the 3D one.
For the record, 7.5-1 made all screen black except the mouse cursor when a 3D app was focused, and back to normal when unfocused, showing all other windows and even the 3D content fine. Composite off "worked" as in 7.4, but seeing there was an update ready (7.5-2) I decided to try that one before reporing this "free screensaver" behaviour. I just noticed there is another update (7.5-3), I will test it soon. GSR -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
