As a subjective measurement in FullHD resolution the super key animation to Activities should be butter smooth with no hickup or steps in either zoom out or zoom in with eg 3 windows. Currently the performance for me is about the same with FullHD on TW with all the kernel tweaks as it is with 4K resolution on another distro without the kernel tweaks. In my case however the comparison in case was against a patched GNOME 3.28.3, so it's not apples to apples. Both testbeds here are using X, not Wayland which seems to perform worse on both. So even though eg the kernel parameters seem to help to an extent, it does not seem it could be said "it's kernel", as also indicated by the fact how GNOME on default Fedora kernel performs just fine too. At the moment unfortunately I don't have anything more to give, I hope to find the culprit together though. You may want to set balance_performance instead of balance_power which was not mentioned here before, but that also is not the silver bullet in any sense. At one point that was critically needed for gnome-shell's optimal user experience but I believe that was fixed in 3.30. -- You are receiving this mail because: You are on the CC list for the bug.
