Created attachment 180104 [details] Showcase of the bug. SUMMARY I initially reported this on virt-viewer GitLab, but I'm unable to reproduce it on Gnome. (https://gitlab.com/virt-viewer/virt-viewer/-/issues/161) When scrolling in the virt-viewer, every second scroll input in the same direction is doubled. STEPS TO REPRODUCE 1. Create a Linux VM in virt-manager. 2. Open a web browser. 3. Scroll in the same direction. OBSERVED RESULT Every other scroll in the same direction, is doubled. EXPECTED RESULT It should only send one scroll input. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 41 KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.2 ADDITIONAL INFORMATION This bug also affects connections to the VM using different clients, such as Remmina. Oddly enough, Moonlight doesn't appear to be affected. Workaround for this bug: - Launch virt-manager/virt-viewer with GDK_BACKEND=x11. - Use 'Redirect USB Device' for the mouse in virt-viewer, but this makes the cursor invisible.
Do you have a non-default scroll speed configured in system settings?
(In reply to Zamundaaa from comment #1) > Do you have a non-default scroll speed configured in system settings? I'm using the default scroll speed settings, this bug also happens on a clean install of Fedora 41. I've also tried several input devices in case it was the hardware to blame: - Ploopy Adept (QMK, wired) - Kesington Slimblade Pro (USB, wired and dongle) - Pulsar Xlite V2 (Dongle) - Logitech MX Master 3s (Bluetooth and dongle)
I've changed the status back to "REPORTED", please let me know if you need more information.
