I’ve been using the 4K TV connected through HDMI port to a videocard for years with no issues. The TV occasionally goes to powersave mode; when I was waking it up, the screen reappeared with no changes in window arrangement. After a recent upgrade to Plasma 5.24.7 this broke: when the display goes to powersave mode (or if I just switch it off) and then gets woken up, all the windows get resized to tiny ones and get moved to the corners of the screen. This ruins the work: when I leave the computer unattended for an hour the entire screen windows arrangement gets destroyed. This problem reproduces 100% of the time. Does anyone have a similar experience or know the solution?
