Is it normal to get GPU Usage like that? This happens to all my rigs. (5 of them)
That happens when the server changes coins? Or is it not normal?

Tip: Add a backup pool (non-clevermining) so you don't loose out on hash time during coin switches.
This doesn't look like coin switches which are done without interruption.
For backup pools: I recommend setting another CleverMining regions as your backup pools.
If that's the case, then I agree! Add another region as a backup pool.
