Graphics are really smooth. Window borders have gone all wonky... not glitching, just... different. And I can't seem to change them back. http://dl.getdropbox.com/u/455435/LiveJournal//Metacity.png http://dl.getdropbox.com/u/455435/LiveJournal/Compiz.png (The "Metacity" screenshot is what the window borders used to look like all the time, and still look like in Metacity.)
I also can't seem to grab the cube with the middle mouse button anymore... Somehow I remember being able to rotate the cube with Ctrl+Alt+Button1 or also with the middle mouse button... but I only see one "initiate" shortcut setting, so I don't know how to get it back to doing both. Hmm. Overall though I think these are small problems for which I just need to find the right settings. I haven't seen any problems with the graphics so far. Are there any specific tests I should do to try to provoke it? --Thomas On Sat, Jun 6, 2009 at 5:23 PM, Thomas <taf...@gmail.com> wrote: > Alright, I'll give it a shot. > > --Thomas > > > On Sat, Jun 6, 2009 at 4:56 PM, Martin Pitt <martin.p...@ubuntu.com>wrote: > >> Thomas Foss [2009-06-06 13:18 -0000]: >> > Quick question... does these freezes only happen when Compiz is enabled? >> I >> > think I have this bug (because I've got a 965GM chipset and Compiz is >> > disabled), but I've never had any freezes.
