I can replicate the bug on my laptop that has a 120Hz screen. What's interesting is that I also experience the bug in KDE (Wayland or X11) as well, so I'm not sure it's a GNOME issue alone. I suspect it's an issue with either the GPU driver or firmware, since my laptop has the same GPU, and I have another laptop that has Tumbleweed with an Intel GPU that does not have this issue, though it's only a 60Hz display. I first noticed it two weeks ago, so it might have been with the kernel firmware update around snapshot 20241022. Laptop: Lenovo P14s Gen 5 AMD CPU: AMD Ryzen 7 PRO 8840HS GPU: AMD Radeon 780M
