This is the video demonstrating the issue on my end: https://youtu.be/D2HDOnXup0k 1965344 1 nekohayo 2023-07-06 07:30:35 -0700 Also, I forgot to mention: this is Epiphany 44.3 with WebKitGTK 2.40.3, running atop GNOME 44.x on Fedora 38 with open source AMD "Pitcairn" Radeon R9 270 graphics, using a normal wired mouse (Logitech MX510, not some fancy high-resolution gamer mouse), default mouse acceleration settings. The mouse cursor size does not affect the observed behavior. GTK animations are turned off (set to "Reduce Animation" in GNOME's Settings). 2148557 2 fujii 2025-10-05 08:27:18 -0700 Pull request: https://github.com/WebKit/WebKit/pull/51835 2148645 3 476973 fujii 2025-10-06 00:44:11 -0700 Created attachment 476973 mouse event test 2149024 4 ews-feeder 2025-10-07 01:39:06 -0700 Committed 301119@main (28387ea7e59d): <https://commits.webkit.org/301119@main> Reviewed commits have been landed.
