Hello David !
Thank you very much for this QT new version.
I have tested it both on Windows 7 and Windows 10 (64 bit) with Gimp 2.8.22 and it works great !!!
Since I am a Krita user I have tested their G’mic version with today’s new version (2.3.1).
With Krita the G’mic version (2.0.3) is extremely buggy on Windows 7 (64 bit) to the point most filters do no work properly.
Luckilly, on Windows 10, G’mic (2.0.3) work much better even though, IMHO, it is not on par with Gimp 2.8.22 where the same G’mic filters I have tested work always fine.
To help Krita developers, I have even submitted a crash report :
