Comment 23 for bug 1690719

I too experience this bug, and it makes GNOME on Wayland really hard to navigate with the mouse on my poor AMD Sempron (1 core, 2.2 GHz).

If I was to measure the cursor in frames per second, I would say that normally and under X I have 60 FPS. But as soon as something starts loading under Wayland (be it icons or menus or whatever), it drops to 0-2 FPS, sometimes even less than that. E.g. if I open the calendar popover, and just move the mouse to the right corner to open the system menu, the mouse stutters as soon as it enters the hover area until the menu get's loaded. While loading the GNOME Shell I am unable to move the cursor at all, although I can move it without the problems with no lag under X, even before the noise background is drawn.

I could live with this, but the sad part is that the keyboard is affected, too. If I search in the Activities overlay for let's say "nautilus" it's not unusual that I get "nauuuuutilus" or "naaaautilus" instead, which is really bad, because if start deleting the characters with backspaces, it lags too, so I end up with the whole word deleted.
