It is not a big trouble, but maybe someone had some experience like I am. In Trixie 6.12 desktop, when I try to move icons - sometimes mouse pointer changes to icon you moved. Reboot or logout/login helps. Maybe someone have some ideas how to fix that. Or maybe a quick mouse pointer reset command?..
Thank you.
I’ve had that happen on normal pis also. It’s just some graphical bug in Wayland.
It is not a big problem, but sometimes it makes me angry. I like to make my desktop very “perfectionistic”. And this is… Ah… 
Ok. Maybe someone will have some experience in that and will share here.
P.S.: Rex - I am very thankful for your job (making all that OS images).
Greetings from Lithuania!
I fond a solution for the desktop icons drag and drop problem.
Problem - when you try to move icon (or icons) on the desktop, it will stick to mouse pointer and will be there till you reboot or log-out.
Solution is to edit ~/.config/libfm/libfm.conf and at the bottom of the [config] section, change gestures_touch_only=0 to gestures_touch_only=1 and then save the file and run pkill pcmanfm to restart the desktop.
I edited that file as admin, using a terminal. Pkilled pcmanfm. Additionally rebooted uConsolle. And it works. No any bugs with moving icons.
P.S.: But, as I think - this is suitable for non-touch devices. Because with this fix we are affecting touch screen devices logic.
