Hi, first post here. Great forum! I believe you can help me with this font issue since I've read similar posts here but still can not solve my own issue which is very specific to one app. This is Samplitude and it is a music production app. Of course I've asked help from the company but they seem incapable to help. From Win 10 64bit 1703 and ever after there are some fonts on the "mixer" window that get small and blurry. Very difficult to see and work with. After lots of investigation I noticed the following: I subscribed to Windows Insider to get fast ring Insider builds. I notice that every time directly after a new Insider Build update is finished, Samplitude fonts are normal (big and clear). After the first sign out (or restart) they get again small and blurry and they stay like that forever (or until the next windows build update). This has also been happening with the public major updates 1703 and 1709. There is some setting that windows change after every build update and change again after the first sign out and it affects the Samplitude mixer fonts. I upload screenshots of before the sign out (normal) and after the sign out (problematic). You can clearly see there what and how is being changed. Other text in Samplitude or anywhere in the whole OS (as far as I've noticed) is not altered. I've also taken note by screenshots of some registry values that have to do with Cleartype, screen settings, etc. There is absolutely no change in any of these values (I can provide details if needed). It is NOT a scaling issue. The way the text is problematically rendered stays unchanged with any other scaling percentage and even with no scaling (100%). The scaling setting has no effect on this issue (and I do sign out after scaling setting changes). If you can pinpoint something somewhere... Thank you!
