You need to make your handler faster.

Browsers can drop events if a handler for that event is still running, so you need to get out of the mousemove handler asap. You could try to optimise the code there or defer work till after the mouse movement is complete. Drawing is probably the slowest thing you are doing, so you could store the mouse movements in memory and draw later. This would not update the display until drawing had finished but it would otherwise work better.
