Hello Bernd,

I've looked into this, technically it's not a regression. Wine evolved :)

First, the app seems to be Wine aware = bad

--- snip ---

0023:Ret  KERNEL32.GetModuleHandleA() retval=7bc10000 ret=0055062e

ret=00550642
0023:Ret  KERNEL32.GetProcAddress() retval=7bc2680c ret=00550642 
--- snip ---

I've seen apps that break just because they try to work around some (older)
Wine insufficiencies.
Wine is a moving target hence a workaround might become superfluous or harmful
at any time.

Tidbit: The app wants to make use of Direct2D - which might prove useful later
for testing when Wine gets more mature in that area.

The actual problem is the incomplete DirectWrite API.

You can work around by disabling builtin 'dwrite' component in settings or
start using:

--- snip ---
$ WINEDLLOVERRIDES=dwrite=d wine ./X32-Edit.exe
--- snip ---
