--- Comment #13 from altosch <a...@tosovsky.eu> --- I'm starting to suspect it's due to the wireless mouse. I have a regular wireless mouse connected via USB, not bluetooth. https://support.hp.com/us-en/product/details/dual-mode-mice/28254823 Out of desperation I replaced it with a regular mouse on a wire (same USB port) and for several days the problem did not occur. I put the wireless mouse back on and right after the first reboot for updates it got stuck again. Either the mouse is defective, or Plasma has somehow become less tolerant of some signal delay, or something like that. I'll test it some more and let you know. -- You are receiving this mail because: You are watching all bug changes.
