So, did a complete restore to bookworm and then upgrade again. Some issue as before! So it is really a bug, However, also the freeze I mentioned before appear again, thus it possibily might also be an X related issue. Not sure about this....
I filed a bugreport of this issue directly to the KDE group (including a small video), and got feedback from them: They say, the kde developers will no more work on any 6.3.X versions, as this version is too old. They are working now at 6.4 and this is the version for plasma 6. I hope, debian will include this version into its repository, or is this to new? Of course I understand, debian software in stable is a little older, but I have a little hope, taht after the official release the libs will be upgraded soon. Just a hope, please do not misunderstand me! Let us see, what the future will bring. Best Hans
