I think it'd be ideal if browsers could hide this problem from developers (with command logging, snapshotting or other tricks) until improvements in OS/drivers/hardware make this a non-issue (e.g. if the OS can notify applications before gfx context is lost, then browsers could snapshot then and problem will be gone for good) Until then great performance can still be achieved with some heuristics and accepted risk of loss, e.g. don't snapshot for 1/10th of a second after canvas has been cleared, don't log commands from requestAnimationFrame() etc. -- regards, Kornel
