Toggle Tiling shortcut (Meta+T) triggers after multiple presses

Help

The global shortcut Meta+T, which is assigned to Toggle Tiling (built-in KWin tiling system), does not activate reliably. The action often triggers only after multiple presses of the shortcut. No other action is assigned to Meta+T, and no KWin scripts (Bismuth, Krohnkite, etc.) are used.

The shortcut does not trigger on first press.

  1. Often it requires 2–5 presses before KWin enters tiling mode;
  2. Sometimes it activates and immediately deactivates (as if the shortcut was interpreted twice);
  3. No conflicting shortcuts exist;
  4. I had this problem before but it went away with updates, but now it reappeared

i would try this with a different keyboard…. sounds hardware related.

If there’s no available keyboard, you can at least confirm it by testing it with a new USER.

I found the cause of my issue with Toggle Tiling: it’s related to having a secondary display enabled. When the secondary display is active, the tiling manager is not reliably activated with Meta + T. This appears to be a bug, so it probably needs a ticket to be filed.

It turns out I’m still not sure about the root cause. On my other KDE Neon system (with all latest updates) running Wayland without a secondary monitor, I’m seeing the same issue, but in a more severe form. There, the Meta+T toggle almost never successfully activates the tiling manager. Instead, I only observe brief screen flickering and momentary text blurring, after which nothing happens. One thing is certain: this occurs only under Wayland and never in an X11 session.

I suspect this is related to the blur effect not activating correctly. I tried disabling Blur in Desktop Effects, but it didn’t help.

I am happy to inform you that the issue now has been fixed with KDE Plasma 6.6.1 bugfix release, thanks to bug report #515940. It turns out the problem was related to the key repeat delay.

The smaller the key repeat delay, the harder is is to open the Tile Editor. The issue appears to be that the shortcut toggles when the key is held down, rather than only triggering once.
