Hi,

I am using the latest emacs 26.1 compiled with msys2/mingw64.
There is problem for a few weeks.
I am not able to give a recipe to reproduce it but the symptoms
are :
- slow ido behavior, much slower than it used to be
- sometimes erratic behavior with the keyboard events
Example: M-x find-library <some string>, get a bunch of choices,
try to navigate them and the cursor jumps erratically between choices...
before trying to enter the debugger, then emacs is stuck and I have
to kill it.
The performance issue has also been reported here:
https://github.com/DarwinAwardWinner/ido-completing-read-plus/issues/143
(probably wrong place to report it btw).

Don't know if/when I will find time to investigate.
But if anybody has suggestions where to look I'll do my best.

Regards,

Fabrice
