UI messed up on 4K

Didn't know where to post this issue as it applies to all Adobe programs. I'm on W10 with a 4K display. The UI on PS and every other Adobe software I'm using is messed up. "Trembling" menus, some menus not appearing at all, palettes that's acting weird where I'm not able to drag and expand them, micro text / ultra small UI text in most sections and all sorts of stuff that makes any Adobe software useless on a 4K resolution on W10. My machine is very powerful stationary graphic work station and everything else is working in terms of UI rendering. My MS Office applications are all scaling nicely in 4K. The problems are only occurring with the Adobe programs. I also checked with a buddy on W10 with a different hardware setup with a different graphic card and he had the same issues.

I've tried to alter scaling in the OS setup to 200%, 150% etc but it doesn't provide a consistence or correct results. Sometimes the super tiny micro text goes away in PS but is still there in Bridge and InDesign for instance. It's basically a fines mess on 4K. One would have thought that Adobe being a design software company should render perfectly on 4K display but obviously not. I contacted MS to see if they had any answer to this but they basically told me that I had to contact Adobe about this. I obviously can't keep on working with a destroyed Ui that doesn't work on a 4K display so my closest option is going back to 2560x1440 display where the UI scaling is perfect in the Adobe applications.

What's causing these issues? I have of course Googled this and I see that there's alot of problems with running Adobe CC on a 4K W10 setup and the theories to why this is are many. It's not working, that's for sure!
