Intellij 2017.2 does not scale

Question

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?

Answer 1

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=false

Then restart. Sorry for the inconvenience.

gsettings set org.gnome.desktop.interface scaling-factor 2
