SUMMARY

In the settings window for a particular notification, there's a small "notification" icon, which can be seen in the screenshot.

If the window is on the primary screen with 4k@200% scaling, it shows a blue icon, however, if it's moved to the secondary screen with FullHD@100% scaling, it shows a white icon. 

Both screens have an effective resolution of 1920x1080, thus I would have expected that the icon does not change.

I have noticed something similar within the GTK app Dino v0.3. The SVG(?) icon of a channel does not scale correctly when the dialog is moved to the secondary screen (fullhd@100%) in comparison to the primary screen (4k@200%). Though, this could be a different bug?
