Tested on Ubuntu 20.04 with GNOME 3.36.8 + Wayland with: Version: 7.5.2.2 (X86_64) / LibreOffice Community Build ID: 53bb9681a964705cf672590721dbc85eb4d0c3a2 I made sure to zoom out a bit so columns A to K were visible. - With gtk3 VCL, no slowdown (although keeps scrolling for a bit after releasing the key) - With kf5 (cairo+xcb) VCL (window is GType:MetaWindowXwayland, so goes through Xwayland), same slowdown as in video, the interface sometimes unresponsive for a few seconds after stopping the scroll. The scroll takes the same time to get to the top, but it's the view that does not refresh frequently, hence the large jumps. - With kf5 (cairo+wayland) VCL (window GType:MetaWindowWayland, so Wayland native), no slowdown. If you use Wayland, you can see if using native Wayland works better by launching LibreOffice with extra variables from the command line, for example: SAL_USE_VCLPLUGIN=kf5 QT_QPA_PLATFORM=wayland libreoffice7.5 Referenced Bugs: https://bugs.documentfoundation.org/show_bug.cgi?id=146014 [Bug 146014] [META] Poor Scrolling Performance -- You are receiving this mail because: You are the assignee for the bug.
