When using Looking Glass under Wayland (specifically with the Hyprland compositor), I’m experiencing scroll lag and inconsistency with my Logitech MX Master 3 mouse. The scroll wheel, which features high res scroll, is not behaving as expected: scrolling is either slightly delayed or doesn’t register at all. However, when I switch to an X11 (i3) session, the problem disappears entirely. Additionally, using a different mouse with a conventional scroll wheel (no smart scroll features) works flawlessly under Wayland. Mouse Model: Logitech MX Master 3
A short video demonstrating the issue is available here:
Yes, I tested it in Sway and it worked fine. Is this an issue specific to Hyperland, or is it perhaps a missing option in my configuration? What is your opinion on this?
EDIT: I wiped my entire Hyperland configuration and tested it with a ‘fresh’ configuration, but the issue persisted.
I have found the cause of the issue. In the Hyprland configuration, there is a setting called ‘emulate_discrete_scroll’. Setting this to 0 disables Hyprland’s emulation of non-standard (high-resolution) scroll events.
After applying this change, scrolling in Looking Glass works again. The scroll speed is now very high in LG, but I think I can adjust that elsewhere.
