Windows 10 1903 Update Breaks GDK_SCALE

[peidaqi]

Please fill out the below information:

• Your Windows build number: 1903

• What you're doing and what's happening:
  Running Terminator terminal emulator with VcxSrv on HiDPI screen.
  Prior to 1903 update, I can add an environment variable in ~/.profile :
  export GDK_SCALE=2
  And this would get a 2x scale for GDK applications.

• What's wrong / what should be happening instead:
  The previous breaks with 1903 update.

• Strace of the failing command, if applicable: (If some_command is failing, then run strace -o some_command.strace -f some_command some_args, and link the contents of some_command.strace in a gist here).

• For WSL launch issues, please collect detailed logs.

This submission is not WSL actionable. WSL writes bytes out socket localhost:6000 and does not know the semantics of GDK_SCALE. The place to direct the question would in forums related to those products (GTK and VcXsrv). You'll probably get better answers there by replicating your scenario under a VM like Hyper-V or VitrualBox rather than WSL. Ref #637 (message). Tag somewhere between external and linux-behavior.
