https://bugzilla.novell.com/show_bug.cgi?id=411587 Summary: Very slow to switch desktops Product: openSUSE 11.0 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: KDE3 AssignedTo: kde-maintainers@suse.de ReportedBy: cschum@novell.com QAContact: qa@suse.de Found By: --- Under some circumstances it's very slow to switch virtual desktops. I'm not sure what the exact conditions are, but here is one way to reproduce it: 1) Open five nedit (www.nedit.org) windows. 2) Switch to another virtual desktop 3) Switch back to the desktop where the nedit windows are 4) Experience a big delay. You can watch the window decorations being painted for something like two seconds before the desktop becomes responsive again. -- 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.

I use the exact same nedit package as on 10.3, where the problem doesn't occur, so I doubt it's a general problem of Motif apps. It certainly was triggered by a change in the X server (or some other component of 11.0). The problem even occurs when all nedit windows are hidden by other windows. If it helps, I can trace the x-traffic. How do I do that? -- 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.

I explained to him that I will put this on the back burner. The only thing I've done so far is to add time stamps to my X protocol tracker so that I can compare runs of different server versions. One needs to plug this between nedit and the server and collect all traffic from the point the desktop with nedit running gets exposed until all window content is drawn. This will show which events and requess were sent and how much lag there was between them. -- 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.

I am a big user of nedit and this hurts me a lot. That being said, I do not think the problem is limited to nedit, even though this may be the application which exposes it most prominently. Running Xfce, I can also reproduce the problem by opening several terminals (/usr/bin/Terminal). While switching to desktops with other applications (firefox, claws-mail, konversation) is very fast, switching back to the desktop with the terminals is not so fast (although not as slow as with nedit.) The more terminals, the slower. Having many open windows isn't the problem though - I can open two dozens file managers or mousepad editors and it doesn't hurt desktop switching at all Bumping severity accordingly - this is _very_ annoying for daily work. Please let me know if I can do anything to help solve this issue. -- 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.

Edit /etc/X11/xorg.conf and add: Section "Extensions" Option "Composite" "Disable" EndSection Restart X, desktop switching will be fast again. This strongly suggests that the slowdown if caused by the compositing extension. -- 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.
