Description Bruno 2025-07-05 09:07:53 UTC 
SUMMARY
When creating a custom tiling layout, one of the zones consistently disappears after logout or restart.  Zones are created using Meta+T, it works as expected during the session but one zone at the bottom of the secondary monitor in portrait mode always disappears after logout or restart.

STEPS TO REPRODUCE
1. Create a custom tiling layout.
2. Restart or logout.
3. Meta+T shows one zone missing from before restart.

OBSERVED RESULT
One zone at the bottom is missing.

EXPECTED RESULT
All 3 zones from before should be there.

I'm observing the same behavior, and it's also happening to my monitor in portrait mode. It's my leftmost monitor and I'm on plasma 6.4.1
Comment 2 i 2025-08-01 09:07:41 UTC 
Exact same situation here - left-hand portrait monitor constantly loses the tile layout, happening since KDE 6.4.x.
Comment 3 dajake1337 2025-08-03 13:26:19 UTC 
I too experience this. Same setup. Left hand portrait Monitor doesn't save tiling config. Also since 6.4.x
