https://bugzilla.novell.com/show_bug.cgi?id=659406 https://bugzilla.novell.com/show_bug.cgi?id=659406#c4 --- Comment #4 from Lucio Chiappetti 2010-12-21 09:45:38 UTC --- I saved the above commands in a file and sourced it. I replied t to the various questions Do you want to reject the key, trust temporarily, or trust always? [r/t/a/?] (r): Reviewing the log a posteriori I note the following two lines 'libtalloc2' is already installed. No update candidate for 'libtalloc2-3.5.4-5.1.2.x86_64'. The highest available version is already installed. Later I got this message Problem: nothing provides libtalloc.so.2 needed by Mesa-32bit-7.9.801-57.1.x86_64 Solution 1: keep obsolete Mesa-32bit-7.8.2-1.3.x86_64 Solution 2: break Mesa-32bit by ignoring some of its dependencies Choose from above solutions by number or cancel [1/2/c] (c): I replied 1, I hope I did the right thing The procedure ran to the end, and said There are some running programs that use files deleted by recent upgrade. You may wish to restart some of them. Run 'zypper ps' To play safe I logged out and rebooted. However after that I tried (as root running KDE, and as an user running fvwm) to create both an IDL graphics window, or a graphics window with my application, and the backing store problem I had persists : - backing store is honoured when the window is (partially) obscured (all wm's) or moved to a different page in same desktop (fvwm) - backing store is not honoured when the window is iconized or moved to a different desktop (all wm's) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Egbert might remember more details, why it is disabled by default meanwhile. I believe there is a reason for this. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The Xserver may provide it by it's own discretion. Backing store was meant as a speedup feature not to preserve the window content for programmers who want to get around handling expose events. The behavior of backing store has change since SUSE 9.2, however since the current behavior still remains within the X protocol specifications this is not a bug. The application needs to be fixed instead. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
