Seems the bug only happens when using non integer fractional scaling (such as 2.5x or 250%). When using 2x (200%) mouse still scale ok. And when fractional scaling disabled and setting 200% scaling, also mouse ok.
Found the following errors when setting to 250% fractional scaling : gnome-shell[4069]: Bug in client with pid 13356: Cursor buffer size (64x64) is not an integer multiple of the buffer_scale (3). gnome-terminal-[9176]: ../../../gdk/wayland/gdkcursor-wayland.c:242 cursor image size (64x64) not an integermultiple of scale (3) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/2018603 Title: Inconsistent cursor size with fractional scaling Status in gnome-shell-extension-desktop-icons-ng package in Ubuntu: Triaged Status in gtk+3.0 package in Ubuntu: New Bug description: When fractional scaling is enabled (I use 250%), the mouse cursor becomes very large when hovering over the desktop and in some applications.
