Description Alexander Potashev 2025-05-04 18:12:05 UTC
SUMMARY
Cannot open "Toggle Tiles Editor". Pressing keyboard shortcut for "Toggle Tiles Editor" does nothing.

STEPS TO REPRODUCE
1. Verify that Meta+Q opens activity switcher (this is to make sure I can use the Meta key)
2. Press Meta+T.

OBSERVED RESULT
Nothing happens. Letter "t" (or "T") is entered in a text input, if one is focused.

EXPECTED RESULT
Should open the Tiles Editor.

Works for me on Wayland. Does it work there for you, or is it also broken on Wayland?

This discussion seems to be relevant: https://discuss.kde.org/t/tiles-editor-shortcut-stopped-working-after-6-2-2-upgrade/24915 - particularly the "solution" response (which is not quite a solution, rather a workaround). TL;DR: increasing the key repeat delay alleviates the problem.

I started getting this after upgrading to 6.5.2 but it probably lurked earlier (I didn't need to edit tiles for some time). The problem fairly consistently reproduces with the keyboard delay of ~400ms and below; fairly consistently doesn't reproduce with the delay of ~500ms and above (could be machine specific? Doing this on Lenovo X1 nano gen2, FWIW).

In the search of the reasons, I opened QDbusViewer and discovered that whenever the tiles editor fails to open up, I see globalShortcutRepeated signal being unexpectedly fired. Specifically, after connecting to all the three globalShortcut* signals, I get this sequence when the tiles editor opens:

Received signal from :1.21, path /component/kwin, interface org.kde.kglobalaccel.Component, member globalShortcutPressed
  Arguments: "kwin", "Edit Tiles", 0
Received signal from :1.21, path /component/kwin, interface org.kde.kglobalaccel.Component, member globalShortcutReleased
  Arguments: "kwin", "Edit Tiles", 0

and this when the tiles editor doesn't end up showing:

Received signal from :1.21, path /component/kwin, interface org.kde.kglobalaccel.Component, member globalShortcutPressed
  Arguments: "kwin", "Edit Tiles", 0
Received signal from :1.21, path /component/kwin, interface org.kde.kglobalaccel.Component, member globalShortcutRepeated
  Arguments: "kwin", "Edit Tiles", 0
Received signal from :1.21, path /component/kwin, interface org.kde.kglobalaccel.Component, member globalShortcutReleased
  Arguments: "kwin", "Edit Tiles", 0

So the tiles editor tries to open but just as it is about to show it gets cancelled by another simulated Meta+T event. This reproduces with non-standard shortcuts too, even not involving Meta modifier.
