New DPI not working, Arch Linux

After setting `xrandr --dpi 276` and starting either idea or pycharm the splash screen shows at the correct (large) size. At about 3/4 of the way through the splash screen shrinks to too small, and the application loads with everything too small.

Is there anything else I can try?

Did you change DPI or the font size in the system settings?

Hello Kenny, what if you rollback dpi settings to the original one? 96? Does it work?

Also, you can try to pass -Dhidpi=false to idea.vmoptions file

I haven't changed the font size in the settings. If I override it then I can make things usable, but all the icons are still tiny, so it's not using the DPI settings.

If I set it back to 96 then the slash screen starts small, and remains small. I'll try the vmoption but I suspect it'll do the same.

I'm looking to have it use the 276 dpi to make things larger, so I would want hidpi to be true, I'd think.

Same problem here using Ubuntu 15.04 on a 4k monitor (3840 x 2160).

- set Gnome scaling to 2 (non-Java apps run fine)
- set cursor to 48x48 in Xresources
- tried -Dhidpi=true, no luck

Webstorm 11 EAP has a minor splash screen problem but it looks fine otherwise. I thought it uses the same code base?

Thanks and Regards,
Peter

Followup: PyCharm 5 EAP behaves like Webstorm 11 EAP, i.e. the splash screen is too small at first, then jumps to a clipped version of the right size - but the IDE itself renders ok. Really strange. IntelliJ IDEA is my main concern, though, and should be fixed.

I'm seeing identical results on Arch Linux -- i.e. splash shows up scaled properly, then reduces in size with progress bar at about 75%, then IDE pops up with tiny icons and text.

I'm also running the Clion 1.2 EAP and that seems to work fine, strangely -- both splash and IDE displayed at reasonable scale.

There are numerous open YouTrack issues with HiDPI on Linux using various Jetbrains products (IntelliJ IDEA, WebStorm, PyCharm), so I am not going to open another one.

As mentioned before, WebStorm EAP 11 and PyCharm EAP 5 work with glitches (splash screen size issues) but my main tool IntelliJ IDEA is not useable under Ubuntu 15.04/10 on a HiDPI monitor. Strange, since these EAPs all use code base 143. It is hard to believe that the latest release is called RC when the Linux version is useless on a HiDPI monitor, especially since this was celebrated as a new feature in a recent blog. The global menu issue is also still pending - it works with 14.1.5 but not with EAP 15.

Are these issues going to be fixed for the final release/is there any progress?

Thanks,
Peter

Please check Idea runs on the same JDK version as minor IDEs (latter started to bundle the JDK).
We disabled global menu integration by default since it causes crashes.

I finally got IntelliJ IDEA 15 to render correctly on my 4K monitor under Ubuntu 15.10 by comparing the appearance and editor settings against WebStorm 11 EAP. I had set non-default font sizes before which must have caused the problem (tiny fonts/icons). I reset them to default once - and now I can set them to any size without further problems. Strange - but all EAPs now behave the same :)

@Maxim: Regarding the global menu problem on Linux - all other Java applications (SmartGit etc) work fine. IDEA 14.1.5 handles the global menu correctly - what is the difference to IDEA 15? The parameters (Linux version, JDK etc) are exactly the same.

Thanks,
Peter

See https://youtrack.jetbrains.com/issue/IDEA-141725 for the details about the global menu issues and why it was disabled.
