Fresh install of Antergos with Deepin - High DPI scaling is not working

[mdunc]

I know this was fixed at one point, but high DPI scaling in Linux still seems to be having some issues. This is a fresh install of Antergos using Deepin as the desktop. DPI scaling does not seem to be working correctly at all much like before. I have also tried qtpass-git from AUR and the results are the same.

Here is what the settings menu looks like. It takes up nearly 1/4 of my monitor.

If I run it like this QT_AUTO_SCREEN_SCALE_FACTOR=0 qtpass, it looks perfect. I'm not sure if this is an issue with qtpass, qt, or the way deepin works (first time I'm using deepin), but qtpass is the only application I've had an issue with so far.
