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?

  • I'll also point out a really similar question of your asked very recently: How to force hiDPI scaling mode on boot in Pop!_OS/Gnome. I would suggest that you mention it directly so that you can distinguish these two questions -- so that any well-meaning close-voters don't mix them up. Commented Jul 17, 2019 at 22:38
  • Is the issue that your app scales properly in CentOS but not in Ubuntu/Debian? Or does your app also not scale properly in CentOS too? Commented Jul 18, 2019 at 1:20
  • @WinEunuuchs2Unix This is an issue consistent with both Ubuntu/Debian and CentOS Commented Jul 18, 2019 at 2:56

For easy launching in HiDPI make these changes to the desktop shortcut, for example with nano editor:

sudo nano /usr/share/applications/com.blackmagicdesign.resolve.desktop

change the Exec line value:

Exec=bash -c "QT_DEVICE_PIXEL_RATIO=2 QT_AUTO_SCREEN_SCALE_FACTOR=true /opt/resolve/bin/resolve"
