Thank you, I tested the new values and it all works as expected for me. However, not sure what it is but the 225% value seems to change the rendering in an unpleasant way. Not sure if it's only not being used to it, but for the time being it feels more "comfortable" reverting to 200% and upping the font scaling a bit, as I did before.

This is insufficient as 200% is too small and 300% is too large. The missing fractional scaling options are dealt with in bug #1687246. However, the currently available experimental feature to enable fractional scaling (provided in the bug description of #1687246) does not solve the problem on my machine: gsettings set org.gnome.mutter experimental-features "['scale-monitor- framebuffer']" After applying and rebooting, the options offered change to 100, 125, 150, 175, and 200%. Note that there is no value larger than 200% which is too small on this display at least for me. In addition, the 25% steps enabled by the experimental option seem too far apart. With 200%, I am using a font scaling value in Gnome Tweaks of 1.20, so I suppose a fractional scaling of approx 240% would be equivalent. In bug #1687246, Daniel van Vugt (vanvugt) advised to open a new bug for gnome-control-center and added that "gnome-control-center seems to limit the scale to 200% on some machines, 300% on others. And I think I have seen 400% offered in some cases. I don't know why, but the inconsistency is definitely annoying." [ Test case ] In a setup with a display with HighDPi resolution (higher than 2880x1800) - Open gnome-control-center display panel - Scaling should show 5 level buttons to select - Selecting higher values will show all the selectable values closer to the chosen one - Any value could be used from 100% up to 400% (maximum varies on resolution) [ Regression potential ] Control center won't show any scaling value, or scaling value may be wrong. --- ProblemType: BugDistroRelease: Ubuntu 18.10 Package: gnome-control-center 1:3.30.0-0ubuntu1 Uname: Linux 4.19.0-041900rc5-generic x86_64 ApportVersion: 2.20.10-0ubuntu11 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon Oct 1 19:29:11 2018 InstallationDate: Installed on 2018-09-13 (17 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Alpha amd64 (20180912)SourcePackage: gnome-control-center UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1795483/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
