I am in the process of migrating my PC from 42.1 to 42.3, both with Xfce. At this moment I have a dual boot PC with 42.1 still operational and 42.3 nearly ready with /home and /usr/local applications copied from 42.1 to 42.3 and tested nearly all my applications successfully. But I am unable to get the kdepim applications working. When I start any of them, the result is only an extremely wide window (maybe 20x the width of my screen) and which is only grey with some blacks. No menu items, etc. It looks as if it is a very much exploded window that is shown on my monitor, nearly uniformly grey with a few bands, but there does not seem to be any contents on it. The only thing I can do is close it (from the drop down menu on the title bar), or drag it around (with Alt-mouse). That is how I could see that it is indeed very wide and, to a lesser extent, high). I have installed, reinstalled, etc, but this behaviour remains
I have a separate PC as mail server which runs autonomously without peripherals with 42.3 and Xfce, and I have installed (for testing) kdepim apps on it. With ssh -X I logged in from my PC and started korganizer, but the resulting window on my PC was the same, although it was much slower to display. Finally, I hooked up monitor, keyboard and mouse to this server and started again korganizer locally and then I got the normal korganizer window as it should be.
I now believe that the problem is not the kdepim application itself but the connection to the X server on my PC. But all other applications do not have any problem, so I am somewhat exhausted in my options to look for solutions. I have looked at some system logs, but they seem rather normal.
I would appreciate any indication for where to look for what is amiss in my 42.3 setup on my PC.
