Jerky mouse movement when using SDL2 backend on Linux
It only seems to affect the cursor on the canvas as movement over the UI is smooth. It's especially noticeable when using the brush grab tool and also when using the magnifier.
I have a high polling rate mouse and attempted to remedy the effect by increasing the merge movement option by 1 a couple times to no avail. The X11 backend works fine and SDL 1.2 works if I increase merge movement to 2. It's probably a bug in SDL2 but I figured I'd say something anyway.
