Btw, I just noticed that some drop down windows, such as the ones in the Chromium Snap, also have a little bit of pixelation in them when vsync is active in nvidia-settings.

Well, this is what I found works thus far: - disable both "vsync" and "allow flipping" in Nvidia-settings - now everything is buttery smooth again; all animations, apps, games and more - doing this will introduce lots of tearing on the Gnome desktop and applications though - then force full composition pipeline to get rid of the tearing by adding this start-up line to Ubuntu's start-up applications: nvidia- settings --assign CurrentMetaMode="nvidia-auto-select +0+0 {ForceFullCompositionPipeline=On}" - Use Wayland alternatively: Wayland doesn't have any of these issues at all, it's a buttery smooth fully vsynced experience ootb, but a bunch of new problems arise instead: Can't set global hotkeys for recording in OBS, OBS recording performance is pretty bad, Gnome folder windows start flickering somestimes, Gnome windows glitch out when trying to resize them manually, Steam flickering sometimes, browsers such as Firefox and Chromium have to be set to Wayland mode in order to solve stuttering video playback issues, Nvidia-settings is missing a bunch of settings and features when compared to X11... and more Hard- and Software: - Ubuntu 23.04 - Nvidia driver version 525 (tested) from Ubuntu's additional drivers tool - Core i7 7700 - 32 GB DDR4 RAM - Lenovo Nvidia RTX A2000 workstation GPU - TWO fullHD monitors connected via display port ProblemType: Bug DistroRelease: Ubuntu 23.04 Package: gnome-shell 44.1-0ubuntu1 ProcVersionSignature: Ubuntu 6.2.0-20.20-generic 6.2.6 Uname: Linux 6.2.0-20-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.26.1-0ubuntu2 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Wed Jun 14 14:58:08 2023 DisplayManager: gdm3 InstallationDate: Installed on 2023-05-20 (24 days ago) InstallationMedia: Ubuntu 23.04 "Lunar Lobster" - Release amd64 (20230418) ProcEnviron: LANG=de_DE.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> RelatedPackageVersions: mutter-common 44.1-0ubuntu1 SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2023776/+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
