I asked a similar question about hiDPI scaling here. This question regards fixing scaling on a specific application, the other question is about a universal hiDPI mode.
I am running ubuntu derivative Pop!_OS 19.04 in Gnome. Edit: I have found this issue arises in CentOS, Fedora, and Debian as well.
I built a .deb package for DaVinci Resolve 16 with MakeResolveDeb and it seems to work fine, but it does not scale properly.
Scaling looks similar to this
This is a known (unfixed) issue, as seen here
The solution runscaled doesn't seem to work.
Is there a known way to solve the scaling issue for this specific application?
