Description Nick W 2026-01-11 18:16:37 UTC

I have shortcuts set in Plasma to "Move window to screen X" where, in my case X is 0-4. When I boot, my screens are consistently in the order 0,2,1,3.

After my screens turn off, and I wake them up, they are re-ordered 1,0,2,3. This also matches the screen priority order set in my display config (might be coincidental).
