--- Comment #21 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

refining the summary in order to collect more dupes here.

Lark, an Electron Framework based collaboration tool also suffers from this.
I've mentioned it in bug 50578
(https://bugs.winehq.org/show_bug.cgi?id=50578#c2).

NOTE: The app requires 'winetricks -q arial' to work around bug 32342

I can confirm that Henri's patch from comment #20 works for all Electron based
apps as well. They show the user interface properly.

$ du -sh Lark-3.40.2.exe

$ wine --version
