sp; mf ... leaves cursor visible in the inactive pane

[vefatica]

When I, for example, wt sp cmd.exe; mf 1, the cursor remains visible in the inactive pane. This is unlike moving focus in other situations; normally the cursor is hidden in an inactive pane.

Version number?

That was the 20 release and the 21 preview. I just updated and the same is true of WindowsTerminal 1.22.2408.23002 (preview) and WindowsTerminal 1.21.2408.23001.

And I'm seeing this for the first time when starting the 1.21 release.

That's apparently from

        {
            "id": null,
            "keys": "ctrl+shift+w"
        },

Any idea?

Any more on this?

If you have looked into this you've probably figured out that it's a matter of timing. I can reproduce the undesirable behavior (cursor showing in the inactive pane) with simulated keystrokes (using TCC's KEYSTACK command).

keystack alt-shift-+ alt-left

If I introduce a delay (9/18 second below) before moving focus, the cursor is not showing in the inactive pane.

keystack alt-shift-+ /w9 alt-left

Is the null from you or automatically generated by us? I'm assuming the latter. In that case I think it's a bug in #17162 and I suppose we fail to remove bindings that have no action?

I believe this issue also happens even if all you do is unfocus the application, while the terminal is currently busy with processing output that doesn't move the cursor (= pure VT).

DispatchTimer::Stop neither cancels the pending nor blocks until the queued event is done:

If Stop is called when the timer interval has just elapsed, it's possible that the timer already queued a Tick event. This event will still be raised.

So, when we do "stop the timer, then disable the cursor", we may still get a blink tick.

I don't think I put that null in there.

I found other ways to leave the cursor showing in an inactive pane also. One is to just do the keystrokes quickly enough ... Alt-Shift-+, Alt-Left.
