Bug ID: 521669
Summary: Visual glitch and render context loss on vertical
monitor when pressing Super+T (Independent Virtual
Desktops enabled).
Classification: Plasma
Product: kwin
Version First 6.7.0
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: wayland-generic

Full journalctl log for the kwin_wayland process. It captures the crash cycle
starting at 20:47:30, showing the exact moment the KWin::Tile component is
invoked and subsequently loses the render conte
STEPS TO REPRODUCE:
1. Set up a multi-monitor environment with at least one vertical monitor.
2. Enable independent virtual desktops per screen in Plasma Wayland settings.
3. Press `Super + T` to open the tiling editor on the vertical monitor.
OBSERVED RESULT:
The screen glitches visually. Checking the logs reveals that `tileseditor/qml`
components throw parameter warnings, immediately followed by a continuous spam
of `Could not delete render time query because no context is current`. The
render context for the overlay seems to be lost completely.
EXPECTED RESULT:
The tiling editor should render the grid overlay correctly matching the
vertical resolution without losing the render context.
SOFTWARE/OS VERSIONS:
* OS: CachyOS (Linux)
* KDE Plasma Version: 6.7.0
* Graphics Platform: Wayland
* Hardware: Intel-based MacBook Pro 2020 (32GB RAM)
* GPU: AMD Radeon RX 580 Series (RADV POLARIS10)
ADDITIONAL INFORMATION:
Attached full journalctl log showing the kwin_wayland crash cycle starting at
20:47:30 upon invoking KWin::Tile.
