Description Tom Englund 2023-02-07 10:51:29 UTC

when second hdmi connected monitors enters dpms it "powers off" as in kwin thinks its unplugged. does the same on windows so probably monitor itself being quirky. however when it powers on windows remembers its position and moves back but the virtual pager in the panel doesnt update and show the windows until i move/resize them.

STEPS TO REPRODUCE
1. use dual monitors and virtual desktops.
2. open windows on both monitors.
3. turn off second monitor, then turn it on and watch it restore positions.
4. virtual desktop pager, doesnt update until you do a move or resize of the window on the second monitor.
