When you connect a second monitor it is used in KDE, but when you try to move a window to it, this window disappears to the lower border of the screen when it is moved to the second monitor. For me this problem is a show stopper to use KDE 5. So I am still working with KDE 4. Please refer to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=910494 The Product and Component is only a guess. Please move this problem to the correct one if it is wrong here. Thanks. STEPS TO REPRODUCE 1. Connect a second monitor that is configured to be right of the left one. 2. Move a window from the left monitor to the right monitor. OBSERVED RESULT Windows is going down to the lower border at a certain point. You can't move it up and work with it. EXPECTED RESULT Normal window behaviour as in KDE 4 - it is working there on the same machine. The problem is happening in Debian 9 (stretch). When i use XFCE instead there is no problem, so it is related only to KDE 5. SOFTWARE/OS VERSIONS Please refer to the Debian bug. Version is https://bugsfiles.kde.org/attachment.cgi?id=118819
can you reproduce the bug if you disable the wobbly windows effect?
I tested to deactivate every of the effects without any result. There is no action defined on any of the screen borders. Any other ideas for tests?
What if you move the panel to the left screen edge?
The left screen edge is no problem, but you pointed me to the reason of the problem! I am using an additional control panel to arrange my main applications. So i have the standard control panel on the left side an the additional control panel with my start icons on the right side. It is the right border of the left monitor! So when i move an window over this right control panel the window goes down to the bottom. When i place the right control panel to the top of the screen i can move any window to the right monitor without any problem. Now we know where to search for the problem. In KDE 4 this was no problem, but in KDE 5 there can't be an control panel between the two monitor screens. Thanks for your help to find the problem!

Hmm, this is probably struts/client area related problem. Just to be sure, can you reproduce this problem with the latest KDE Plasma release? You could use Neon Live CD for that purpose for example https://neon.kde.org/download
Sorry, but then a complete new installation of a distribution is needed, that contain the latest KDE version. It's easier to connect an second monitor to a PC that has the needed installation of the KDE - isn't it?
Is the CD-Image running from an USB stick?
Have you updated to the most recent version of Plasma 5.23 in the mean time? Can you please confirm, that it still persists with Plasma 5.23?
With the current stable version of Debian the bug does not exist any more. Betriebssystem: Debian GNU/Linux 11 KDE-Plasma-Version: 5.20.5 KDE-Frameworks-Version: 5.78.0 Qt-Version: 5.15.2 Kernel-Version: 5.10.0-8-amd64 Art des Betriebssystems: 64-bit
Thank you for your feedback!
