Drawing practice clock is slowed [DEMANDE DE SOUTIEN]

Is anyone else having an issue with the timer during practice/class sessions? It often ticks down twice as slow as it should, with one second on the clock lasting for two seconds. It usually fixes itself when pausing and resuming the timer, but still it's cumbersome during practice sessions when some of the 30 second drawings last for 30 seconds and others last for 60. Is there a fix for this?
