The 'fix' introduced problems. Eg. Illustrator is still working fine yet on 100%. I checked Photoshop it's about 150%, not 200% as I previously mentioned. I'm using 17134.112 Windows build and Photoshop 19.1.5. It's too big (~150%). If you don't like the word 'bug' I can say this is a usability problem. I want to make Ps smaller. Can I? No. What about making it bigger? No. Awesome. Look at Illustrator: Do you want small UI? There you have it. Well, a bit small  (100%) but still better than a big (let's say 150%). Want HUGE UI (200%)? No problem. Then Photoshop: Meh. Use this, it will be good for you (~150%), I promise. User: Nooooo Please try out my setup, it doesn't take too long but you will understand the struggle. ... View more

Exactly. The 'fix' fixed the scaling to about 200% and cannot be overridden. Try it yourself. Here is a program which I also use. Set 125% Windows scaling, using Windows 8's method and start Photoshop. (This is needed because Microsoft still did not fix the blurry scaling in latest W10. There are many topics on that.) ...

I also use 125% scaling and I have the same problem. Ubuntu's UI on default roughly looks the same in size as Windows on 125%, so this statement is the point of view, what's normal and what's not. The problem is that Photoshop independently decides what scaling will be good for me. Why? I can decide which one is good for me. The 100% option inside PS was a good alternative, but now it's broken. It made smaller than other applications, but at the same time, it meant more working space. Now everything is overly big and we can't change back, just with a 'main switch' the Windows scaling. So changing the operating system scaling is not the solution, because there was a reason why we increased the size. ... View more
