Preview pane blurry (on HiDPI monitor)

[drakesiard]

In gummi 0.8, the preview pane is blurry, compared with the 0.6 series on my 3840x2160 monitor. It looks like the 2x scaling is being applied incorrectly.

To reproduce: open gummi 0.8(.1) and gummi 0.6(.6) next to each other on a 2x scale display and look at the rendering.

Attached are the two screenshots for comparison:

I am having the same issue (on elementary OS 5.1, i.e. Ubuntu 18.04).

I don't have a HiDPI monitor myself, but obviously this issue will become more problematic over time. I will look into this.

Note to self: start gummi with GDK_SCALE=2 ./gummi to test.
