Jetbrains IDEs don't use user cursor theme

[alapshin]

Issue description

Android Studio doesn't use user's cursor theme.
For example, I have Breeze cursor theme selected in KDE settings but Android studio uses some default theme instead.

I tired different gtk apps (firefox, gimp), different Jetbrains IDEs (idea, pycharm) and even steam (since it also uses FHS environment). All of them respect user's cursor theme.

Android Stuido build downloaded from Google site also respects user's cursor theme.

Steps to reproduce

1. Change cursor theme to something other than default
2. Launch Android Studio
3. Move cursor inside Android Studio window. It changes to default one.

Technical details

- system: `"x86_64-linux"`
- host os: `Linux 4.14.79, NixOS, 19.03pre158246.6141939d6e0 (Koi)`
- multi-user?: `yes`
- sandbox: `yes`
- version: `nix-env (Nix) 2.1.3`
- channels(root): `"nixos-19.03pre158246.6141939d6e0"`
- nixpkgs: `/nix/var/nix/profiles/per-user/root/channels/nixos`

After some tinkering it looks like other Jetbrains IDEs installed from nixpks also have this problem.
Which is strange since versions downloaded directly from website use correct cursor theme.

Same here (with Intellij IDEA). It would be nice to make them respect user cursor theme, because default one looks really ugly.

I tried

My workaround is currently to use the official release (with JetBrains JDK) in ~/opt/idea with an ~/opt/idea-shell.nix consisting of

{ pkgs ? import <nixpkgs> {} }:

(pkgs.buildFHSUserEnv {
  name = "intellij-idea-env";
  targetPkgs = pkgs: (
    with pkgs; [ udev which alsaLib fontconfig freetype pango zlib glib gtk2 cairo gdk_pixbuf atk git ]) ++ (
    with pkgs.xorg; [ libX11 libXcursor libXext libXtst libXi libXp libXt libXrender libXxf86vm ]);
  runScript = "~/opt/idea/bin/idea.sh";
}).env

and

nix-shell ~/opt/idea-shell.nix

to build/start it.

Cursor themes / hidpi cursors seem to work fine in the FHS environment.

Any update on this? It still seems to be an issue on the unstable channel.

[alapshin]

As far a I can tell Android Studio from nixpkgs now uses system wide KDE cursor theme but IntelliJ IDEA doesn't. I'm not sure was it something that was patched in Android Studio upstream or there are some differences between Android Studio and IntelliJ IDEA nix packages.

I confirm this still happens on 20.03 at least (under the gnome desktop) for:

• Intellij IDEA Community
• Pycharm community.

[ataraxus]

Works now on Ubuntu 20.04 with Intelli 2020.3.1

[alapshin]

Yes, I can confirm that it works on NixOS unstable channel with IDEA 2020.3.1 and Android Studio 4.1.1
