Does the bug happen if you start with --temp-basedir?:

Yes.

Description

When in command mode, there is a blinking cursor. Pressing Ctrl-Left/Right moves the cursor word-wise (stops at special characters etc.) and makes the cursor always show while moving around (i.e. when pressing repeatedly it doesn't blink anymore for that timespan). With Alt-B/F (and possibly other combinations I'm not aware of), the cursor keeps on blinking. That makes it hard to quickly jump back and forth, because one has to guess where the cursor is.

Any chance to make that behavior consistent with Ctrl-Left/Right?

[The-Compiler]

Interesting observation! This is done by Qt, and I don't know if there is a way we can cause it to happen with how we move the cursor with those commands.

There is apparently a QWidgetLineControl::setBlinkingCursorEnabled(), but I don't see that being called with false anywhere except for the line edit losing focus (together with d->setCursorVisible(false);). In any case, however, all of those are internal to Qt.

I also tried to find out where Qt actually binds/handles the Ctrl + Arrow keypresses - I believe that's here in QWidgetLineControl, but I don't get what would be responsible for the cursor handling there. It looks like cursorWord* just calls the moveCursor method, which then moves the cursor around - but I don't see how that or anything (commitPreedit(), separate(), *MaskBlank()) would cause the cursor to stop blinking.
