First - If I am getting this right, Magix is now the owner of this product family - not Sony.
I have been using it for some time, even on Windows 10, but I've now moved to a new laptop (for storage and rendering speed purposes). This is also a Windows 10 64 bit machine.
What I am seeing is that the movie studio dialogs are all off - not quite right. The text doesn't fit well - plugins, filters and generators are very hard to interact with - and the actual plugin UI won't scale or change with a window resize.
Also I am finding that all the colour picker dialogs are broken - I get nothing at all. I use generated text overlays in my videos frequently - currently I can only use the default white.
Further information:
Movie Studio Version 13.0 Build 955 64 Bit.
Display resolution: 3840 * 2160 with windows set to 250% scaling. Video: Intel Graphics 530 + NVidia Quatro M1000M.
I've attempted the windows compatibility tool, and attempted to exclude movie studio from the scaling - which seemed to be ignored. I've tried in Windows 8 compatibility mode - which made no difference. It still seems to be ok on the old laptop - which is also Windows 10 - but with a much lower resolution display.
