Hey Guys!
I am happy to announce that after working for almost 10 days we have successfully fixed the issue affecting the latest Mojave Mac versions.
The hotfix is available right now to update version 9.1 for Mac! It is still not 100% perfect but the minimizing issue and disappearing game windows have been fixed. Tested on 1600x900 // 1920x1080 // 2560x1080 // 3840x2160
We will bring you some more news on the future update soon too!
