Version: unspecified (using Devel) OS: Linux KDE 4.4.92 The panel is set to "Maximize panel" via the cashew. If I increase my screen resolution, the panel will not scale with it. It stays the same with, although it should be maximized. If you often plug in projectors with lower screen resolution, comming back to the high will always require you to open the cashew and select maximize panel again. Reproducible: Didn't try
Still there in 4.5 final. (kubuntu lucid backports package) It happens all the time my X server starts with the wrong resolution and I have to adjust it later at run time.
Some more data: My setting: multi-monitor, panel on the bottom edge of the external monitor. For some reason Xorg does not set the external monitor with its full resolution on startup, so I adjust it using the tool from ATI, after which the panel keeps the same width (in pixels), and is aligned on the right border of the screen. Maximizing the panel won't directly work: the panel already believes it is taking all the screen width. So does the configuration extender, which also won't take all width (although for some reason it will be aligned on the left border). Moving the panel to another edge, then back to where it was will make it take into account the actual screen width: that is it still has the same size (not maximized yet), but the configuration extender will now use the full width. And now maximizing the panel will also make it use the full width.
I have a laptop which I also used docked with two external monitors. Since the resolution of the native Laptop LCD is higher than that of the external screens, when I use the laptop undocked the panel does not stretch to the entire height of the screen (I use the panel vertically). When the laptop is docked to and used with the external screens it does shorten to match the screen size.
