im having a little bug omnisphere 2.6.2 works and everything on my fl 11 which is cracked and everything works fine sounds and all but for some reason the screen is not fitted on my omnisphere the gui is fucked up idk why its happen and i cant seem to find any solution past version of omnispheres worked and looked fine but this shit is kinda irritating its like a quarter of the screen is gone i have 64 bit windows 10 pro pc with a 1050 ti i7 8th gen cpu 250 gb ssd

 

I don't know if version 11 has this but if there is a FL64(scaled).exe in your FL Studio install folder. Try running that one with Omni? Just an idea.
Hope you get to work properly
