After recent update to 5.6.1 I can't stretch panel to full horizontal size (1920) while using xmonad. I tried to change panel's width manually in ~/.config/plasmashellrc and set this file to read-only (because plasma automatically changes it), but it didn't work. In previous version it automatically sets to 1920. Button "Stretch panel" in panel settings (may be it have another title in english localization of plasma) doesn't work too. And config reset doesn't work too. In default plasma session (without xmonad) panel width behaves right. Seems like it was caused by this commit: https://github.com/KDE/plasma-desktop/commit/1f01ec6e4e86e395e7867e98b9461704bf6731fa . Screenshot: http://i.imgur.com/dgjU8fA.png Reproducible: Always Steps to Reproduce: 1.Just try to use 5.6.1 plasma and xmonad. Actual Results: Panel can't be stretched to full horizontal size. Expected Results: It should stretches to full horizontal size. ArchLinux, latest version of all packages. Reproduced on desktop and notebook. Screen resolution 1920x1080.
Can you resize it and run "xprop" and click on the panel. Then attach the result.
Edit. Nevermind. Someone's already done that. *** This bug has been marked as a duplicate of bug 359764 ***
