           Summary: Plasma desktop/panel does not react properly when the
                    screen size is enlarged due to higher resolution
           Product: plasma
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: wolters.liste gmx net


Version:            (using Devel)
Installed from:    Compiled sources

Description of problem:
Neither the Plasma desktop nor the Plasma panel do enlarge to the right size when the resolution of the monitor is set to higher values on the fly via xrandr or for example nvidia-settings.
Windows are however resized to the right, higher resolution.

Version-Release number of selected component (if applicable):
KDE4Daily svn version 818795

How reproducible:
This can be easily reproduced with the KDE4Daily image.

Steps to Reproduce:
Load the virtual machine (I used VirtualBox), and log into KDE 4. Use xrandr to set the standard resolution to a value smaller then the maximum. IN my case the maximum resolution is 1280x800, and I've set it to 1024x768 (xrandr -s 1024x768). Log out, you will see the login manager at the smaller resolution. Now log in again, KDE4 also appears at the smaller resolution. Next, use xrandr to set the resolution back to the maximum value. The Plasma desktop as well as the panel don't fill the entire screen, but only the smaller area beginning at the top left. The rest of the screen is filled with a gray area with white blocks.
However, maximized windows do fill the full new resolution. If you try to resize the panel, it jumps automatically to the bottom and therefore at least to the right place (while still not large enough to fill the full width for example).
If I now log out and log in again, and the desktop fits to the high resolution, and also maximized windows fit to the new, high resolution. Only the plasma panel is everything works again. But log out/log in everytime I increase the screen resolution is not an option!

Actual results:
The panel and the desktop stay in the old resolution beginning in the left upper corner.

Expected results:
They should enlarge to the new, higher resolution.

Additional info:
I tested this with nvidia-settings on OpenSuse 11.0RC (with "unstable" packages) as well as with xrandr in KDE4Daily.

This bug sounds similar to Bug 154045, but that one is marked as fixed, while the problem described here is certainly still existent.
