The problems you are experiencing @mobilebackup and @agwin, are most likely due to the way the workaround works. Correct me if I am wrong, but the workaround is asking the graphics system to render a larger canvas (say 2x, 8K or whatever) and scales this down to the viewport size. If an application is not enabled for HiDPI mode, they will be very squished. If you don't have sqaure pixels (like most of us), you will get bad text, and if you don't check for orientation, the viewport will break.
The reason I said this is a fab workaround, but won't hold for production, apart from above, is we are asking the card to render a huge area. If you move windows around or watch video with GPU decoding, the card is going to have to move a huge amount of data around. These are my ramblings, for whatever they are worth. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1870736 Title: [nvidia] Screen scaling 125% gives 200% Status in gnome-control-center package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: Procedure used: 1.
