Bug#897578: gnome-shell: In overview mode, rapid typing results in out-of-order characters in search box

[Rob Johnson]

Package: gnome-shell
Version: 3.22.3-3
Severity: important

Dear Maintainer,

Rapid typing results in out-of-order characters in search box of overview mode.

To replicate:
1. While in a gnome session:
2. Enter overview mode.
3. Type "ter", leaving very little time between key presses.
4. Search box will often contain "tre".

Additional info:

- This only happens in overview mode.  Rapid typing in gnome applications
always results in characters in the same order that the keys were pressed.

- I have carefully checked that I really am typing the characters in the order
"ter".  For example, sliding my finger over the keys 1, 2, ..., 9, results in
out-of-order numbers in the search box (the disorder is non-deterministic).  In
the experiment with the number keys, I never see any missing or duplicate
numbers in the search box, just numbers out of order.

Thanks for looking into this!

Best,
Rob
