Xorg 6.8.2 Nvidia drivers NVIDIA-Linux-x86-1.0-7167-pkg1 XFCE 4.2.1 with Composite functions built and composite enabled in xorg.conf XFCE Desktop is configured not to redraw content on window resize. Resizing the Menu Editor will result in a freeze of the desktop. CTRL-ALT-Backspace does not respond. CTRL-ALT-F1 does not respond. Panel does not animate or respond. Without CTRL-ALT-F1 I can't see if anything else on the system is working (no remote access)... I think the mouse still moves though. With or without 'redraw content on resize' the Menu Editor appears to redraw the content on resize. Without the composite options enabled, the resize of the Menu Editor does not cause a problem. Reproducible: Always Steps to Reproduce: 1. Enable composite functions 2. Open Settings Manager -> Desktop -> Menu -> Edit desktop Menu 3. Resize the menu editor window. Actual Results: Mouse moves, no redraw of windows/panel. No response from keyboard. Expected Results: To be able to continue using the menu editor without a desktop freeze. The fix is of course not to use the composite functions until they are further developed. Should I log a separate bug for the Menu Editor redraw behavour itself.
if the problem appears only when using the composite extension then it's not xfce4-menueditor related... furthermore the composite extension is known to be unstable; i think you should try to reproduce it with other applications and fill a bug report either on GTK+ (if it happens only with gtk based applications) or Xorg website
It's not xfce4-menueditor problem, because bug reproducing with other applications too (for example, with mousepad).
unless you can show it only happens with Xfce it only shows that Xfce isn't in cause here; my prefered explanation is the Composite extension.
