window maximizing behind panel
Attaching with correct file type.

correct behavior with intel driver
By switching the display graphics from discrete to integrated and thus the video driver from nouveau to intel, the problem goes away.
This sounds like some sort of minor bug in the nouveau DDX wrt how it's reporting screen heights wrt WM fixups/etc. Unfortunately I don't know enough about those details to tell what's going on... perhaps you could get an xfce dev to clue us into what we're doing wrong? Although it's telling that _after_ you run the settings, it all starts working. So perhaps we're missing some bit of initialization? Would be nice to know exactly what these things are doing. To further complicate things, this doesn't appear to be a problem with the driver version shipping with the 3.13 Linux kernel tree. I'm not able to replicate this behavior when using the 3.13 kernel releases from kernel.org and their associated nouveau driver. I can reliably reproduce this when using the 3.11 kernel from Ubuntu's 13.10 release and their associated nouveau driver. Going to close this as resolved/fixed. |

Created attachment 92873 [details] window maximizing behind panel Running a 3.13 kernel, built from upstream git repository (commit d8ec26d7f8287f5788a494f56e8814210f0e64be) and the associated nouveau driver from the kernel source tree. When any window is maximized before first viewing the xfce4-panel settings, it maximized behind the xfce4-panel(s). Once the panel settings have been viewed, the windows no longer maximize behind the panel. The settings for each panel have to be viewed, but only once per session. Normally, I would consider this an issue with xfce4 (either the panel or window manager). However, changing the video driver (from nouveau to intel) prevents the problem.
