When the taskbar plugin is in the panel with "Expand to fill screen" enabled, and I do something that changes (increasing or decreasing) the available space, such as adding an item to the panel, removing an icon from the panel, or changing the amount of workspaces (with the graphical pager on the panel), the panel will 'shake' (resizing itself?) for a variable amount of time (~1-5 seconds). The xorg composite extension is disabled. Reproducible: Always Steps to Reproduce: 1. Enable the panel taskbar plugin 2. Enable its "Expand to fill screen" option" 3. Enable the System Buttons taskbar plugin 4. Toggle the option to "Hide" Button 2 (try a few times) Actual Results: The panel resized itself many times before stopping. Expected Results: A single resizing before halting I'm using the AMD64 deb packages (4.2 RC3) in Ubuntu from http://www.it-weber.net/debian/xfce4/
I confirm this behaviour and I suspect this to be the cause of bug #607
Same here... 'expand to fill screen' is the problem I believe... (multiple machines) Harold.
Same problem on my slackware 10.1 with XFCE 4.2.0 compiled by Patrick and taskbar plugin
I can confirm this is happening for me too. 4.2.1 running on Gentoo Linux. For me it tends to happen indefinitely (infinite loop) unless manually rescued. To stop it happening I generally have to click things randomly and bring up menus. It eventually stops with a bit of work.
Ok guys, no need for more confirmations ;-) I know what the problem is and it will be solved in Xfce 4.4. It probably requires too many changes to the panel to add a fix to the stable series.
Won't fix for 4.2, but this problem should not exist in the SVN version (4.3.x).
