Poor font appearance for VS Code snap

The font for the Visual Studio Code snap looks aliased for me (using KDE Plasma in X11 on Fedora 28) (it looks dim and a little blurry). For comparison, the font in the flatpak looks bright and clear (but it is unusable because the flatpak confinement prevents it from accessing system files needed for autocomplete and debugging). Is there anything I can configure to get better fonts in the snap version?

It looks like this issue was already reported a while back here: Vscode fonts - Fedora 28 I don’t know how I missed that when searching before. That thread has been quiet for several months, so I guess there is no quick solution coming…
