TinyCLR RTW firmware bug for G30

I found a weird bug in the latest bits, the G30TH is slow when not on debugger.
Its also in the preview 3 version, the latest that worked OK is in preview 2.

sample code is a simple blink example.

pwmPin.Start();
Thread.Sleep(50);
pwmPin.Stop();
Thread.Sleep(50);

when I have USB cable attached and debugging through VS, or when TinyCLR Config is connected to the device the PWM pin flashes fast, as intended (50ms), when I disconnect cable and reset the device PWM pin flashes slow, like its set to 500 or 1000 ms.

Please confirm this, I spent 4 hours reviewing my code thinking I messed up something.

Use the patch from link below:
