After updating to 2017.2 Intellij IDEA does not scale properly on Dell Ultrasharp U2415b. The icons are very big and the workspace is very small.
I have checked, that Intellij changed something with HiDPI support.
Anyone facing the same problem?
Found a workaround on https://blog.jetbrains.com/idea/2017/07/intellij-idea-2017-2-is-here-smart-sleek-and-snappy/:
The fact is that “the better HiDPI support” is currently limited to integral scale displays only, which is not your case. IDEA should have auto-switched to the previous HiDPI mode on start, but it unfortunately didn’t work for you. The problem should be fixed in the upcoming update: https://youtrack.jetbrains.com/issue/IDEA-173258
Until it’s fixed, please reset the HiDPI mode manually by providing the VM option (Help > Edit Custom VM Options):
-Dsun.java2d.uiScale.enabled=falseThen restart. Sorry for the inconvenience.
