SUMMARY I set a desktop to 1 tile as a quicker method than dragging to the top and hit doesn't expand on a specific desktop. This is the tiling with shift key. Also has flicker in this situation that doesn't occur during 2+ tiles. STEPS TO REPRODUCE 1. Meta-T and delete extra tiles 2. Hold shift while moving window and release left button. OBSERVED RESULT Flicker with no expansion to fill tile. EXPECTED RESULT SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.3.90 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0 Kernel Version: 6.14.6-273-linux-tkg (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 64 GiB of RAM (62.7 GiB usable) Graphics Processor: NVIDIA GeForce RTX 4080 Product Name: X570M Pro4
This also happens in 6.3, right?

Git commit 9b0fd06e14e30c8fa39271fe6b1c0faaee381588 by Vlad Zahorodnii. Committed on 19/05/2025 at 08:33. Pushed by vladz into branch 'master'. tiles: Fix CustomTile::remove() collapsing tile tree too much When a tile is removed and its sibling is empty, the parent tile will be converted in a leaf tile. The problem is that CustomTile::remove() can attempt to convert the root tile in a leaf tile, but we expect the root tile to contain at least one child at all times. This change adds a relevant guard. Note that CustomTile::remove() can be still used to purge all children of the RootTile. This is mainly used by the tiles editor. Window::quickTileGeometry() was also adjusted so it doesn't report a misleading geometry if the window can't be custom tiled.
