Fractional Scaling works for me after update. NVIDIA Corporation GM204 [GeForce GTX 970] Scrolling and 4K videos are very laggy in 125%, 150% and 175% mode. Tested with: - NVIDIA driver metapackage from nvidia-driver-440 (proprietary) - NVIDIA driver metapackage from nvidia-driver-450 (open-source)
1 x 4K-Monitor (125%) 1 x FHD-Monitor (100%) Used this command to see GPU usage: $ watch -n 0.5 nvidia-smi Watching 4k Video (120fps): - no scaling: 25% capacity - with scaling: 65% capacity (sometimes flickering and black screen) No interaction: - no scaling: 3% capacity - with scaling: 6% capacity -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1870736 Title: [nvidia] Screen scaling 125% gives 200% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1870736/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
