Ah, good catch--I updated the variable name in the issue description.

> Running NetBeans 11 on Kubuntu 18.03, GUI text size does not seem to take into account the system's default HiDPI scaling. This was reported in a Twitter thread on https://twitter.com/nicktail/status/1114789604337405952 . Note that Window decorations seem to be the correct size.
> Setting the GDK_SCALE environment variable seems to fix the problem, if I understand the originally reporter correctly. This could probably be done easily from the NetBeans launcher script (netbeans/bin). But it wouldn't fix the problem in multi-monitor setups. We should investigate what could be done to make scaling work properly in multi-monitor setups involving one HiDPI screen and one non-HiDPI screen.
> Before merging a patch to the launcher script, it should be tested on a couple of different Linux environments, using both HiDPI and non-HiDPI screens. Note that the UNIX launcher script is also used on MacOS.
