          Hardware: x86-64
                OS: Linux

It's a regression that makes wine unusable on my machine (the summary states
about notepad but it happens in other applications as well). I didn't try to
debug it myself yet. I guess it's something specific to my machine
configuration.

Regression test points to:

win32u: Move ImeToAsciiEx implementation from winex11.

Using a new WINE_IME_POST_UPDATE NtUserMessageCall call for the drivers.

Steps to reproduce:
 - start notepad
 - enter anything
 - close notepad window
 - application freezes after displaying save prompt - it's not possible to
click on the dialog
