I'm having an issue with blurry tray icons using HiDPI GTK3. I've read to set
GDK_SCALE=2 and GDK_DPI_SCALE=0.5 to get proper hidpi in GTK3 applications.
This works and makes the GTK3 applications scale correctly, except for the tray
icons. The tray icons actually scale fine without those environment variables
set. One other HiDPI tweak I have set is "xrandr --dpi 192", otherwise programs
like Xterm, dmenu and the WM won't scale.
Here are some screenshots:

I get good tray icons with some unscaled menu text. GTK3 applications
themselves don't scale properly as expected.

You can see blurry tray icons, but with properly scaled menu text. GTK3
applications scale as expected.
It seems to me like GDK_SCALE=2 and GDK_DPI_SCALE=0.5 is causing the already
scaled tray icons to scale again. Is there something I can do to fix this? Is
it a bug?
I'm running gtk 3.22.1 on arch linux. I'm using i3-wm, but I've seen this same
issue on xmonad with trayer and on budgie desktop too for non-indicator tray
icons. I'll also note that everything scales fine in gnome desktop on my
hardware which is a Dell XPS 13 9350.
