The window management of Kate has changed recently. It completely breaks working with multiple projects on multiple virtual desktops simultaneously. STEPS TO REPRODUCE 1. Open a document with Kate on virtual desktop 1 2. Switch to another virtual desktop, say 2 3. Open a document there OBSERVED RESULT The document opens in the already existing kate instance on virtual desktop 1. The window manager switches back to virtual desktop 1. EXPECTED RESULT A new kate window appears on virtual desktop 2 with the newly opened document. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 X11 Also tested on XFCE/KWin and on LXQT. Also tested with a fresh user account to rule out any odd settings. ADDITIONAL INFORMATION I've been using Kate for more than 10 years now. The changed window management makes it absolutely impossible to use Kate on multiple virtual desktops with multiple open projects. When clicking a file in dolphin it shouldn't matter if there is an open Kate window on *some other* virtual desktop with *a completely unrelated* project open. Consider you're working on some C project on virtual desktop 1. You created a .kateproject to manage files, set up the lsp server and have lots of .c and .h open in the Kate window. Now you switch to another virtual desktop and need to look in a piece of python that is in no way related to the C project. Maybe you got a phone call and someone is asking. So you open up dolphin, navigate to the project and click the .py file you want. It suddenly appears in your open C project somewhere between the 10 open tabs you were working on before. Also you're suddenly back on virtual desktop 1. Also the "Behaviour -> Open each document in its own window" option doesn't help as Kate now opens a new window even if you drag a file onto an existing Kate window. The option makes it impossible to have more than one tab.
I think it is my fault that this regressed, I can take a look to restore that.

Can you try the linked patch?
Thumbs up for the fast response! I was afraid this might be some intended change, read somewhere on discuss.kde.org that the window management was changed ("for the better") and had the gnome story in front of my eyes... The patch works for me. Thanks again for the fast fix, kate has become somewhat irreplaceable for me.
