Description goo 2024-12-01 17:23:21 UTC
SUMMARY
Using the Shift while moving a window does not recognize the Tile Manager split lines defined by Meta+T. Only the Quicktile options of half and quarter screen are shown (just like without the Shift)

STEPS TO REPRODUCE
1. define tile arrangement using the Tile Manager (Meta+T)
2. grab a window to move/tile and hold the Shift key
3. try to tile the window into one of the tiles defined in step 1.

OBSERVED RESULT
Window will only tile into the Quicktile locations (half and quarter screen locations) as if the Shift key were not pressed.

EXPECTED RESULT
Window should tile into one of the predefined tiles as configured under the Tile Manager Meta+T

ADDITIONAL INFORMATION
dual monitory set up with Asus PA248QV as main and a Dell P2417H as secondary (in portrait orientation).
Tiling using the Shift key works as expected under wayland.

Also of note and may be related: using gddccontrol the Asus monitor shows up as a VESA standard monitor with no controls, while the Dell shows up as the correct model number (display port) even tho both monitors are connected via DP cables.

Adding the x11-only keyword

I can't repro this. I have 2 Monitors (+ TV), tiling is set up on both my monitors with a custom layout and dragging + shift works on both.
This is both when draggin a window by the window bar or using meta+click to drag it.

Since this issue is almost a year old, maybe it was fixed in the meantime?

this was an early version of plasma 6 and i've since moved back to plasma 5 on the LTS track where things work as expected under X11.

so this can probably be closed.

Ok, thanks.

This is still valid. Meta + T does not work also in my system:
Can I debug this further?
