Bug ID: 513081
Summary: Add config option to disable or rebind the Shift
modifier for custom tile snapping
Classification: Plasma
Product: kwin
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: Custom Tiling
Assignee: [email protected]

Target Milestone: ---
Problem: Since Plasma 5.27, KWin's Custom Tiling feature (Meta+T tile editor)
hardcodes the Shift modifier for drag-to-tile functionality. When dragging a
window with Shift pressed, it automatically snaps to the nearest custom tile.
There is no way to disable this behaviour or rebind the modifier key.
This creates conflicts with third-party tiling extensions that also want to use
Shift+drag for their own tiling behaviour. Users are forced to either:
1. Use a different modifier for third-party extensions, which is less intuitive
2. Compile a custom KWin build to modify the hardcoded behaviour
Rationale: Prior to integration into KWin core, tiling was more modular and
configurable. KDE's philosophy has always been user choice and configurability.
Hardcoding a single modifier key without any config option to disable or rebind
it goes against this principle.
Requested Feature: Add a configuration option (either in GUI or kwinrc) to:
- Disable Shift+drag tiling entirely (allowing third-party scripts full
control)
- AND/OR rebind the modifier key (Shift/Alt/Ctrl/Meta)
This would allow users to:
- Use third-party tiling extensions without conflicts
- Choose their preferred modifier key based on their workflow
- Maintain the flexibility KDE is known for
Use Case: Users who prefer third-party tiling solutions (KZones, Bismuth,
Polonium) or have muscle memory from other tiling window managers often want
Shift+drag for their chosen solution, not the built-in tiling.
Technical Note: The Shift modifier check appears to be hardcoded in KWin's C++
source (introduced in MR !2560). Adding a config option would be
straightforward and maintain backward compatibility (default: enabled with
Shift modifier).
STEPS TO REPRODUCE
1. Edit `~/.config/kwinrc` and add the flag `enabled=false` under the
`[Tiling]` section.
2. Save config + reload KWin
OBSERVED RESULT
KWin Custom Tiling still enabled. Shift + drag window uses KWin tiling engine
EXPECTED RESULT
KWin Custom Tiling should be disabled. Shift + drag window is now free to be
reused by another tiling engine.
