Where do I report bugs ?

I'm having graphical issues to the extent I can't play the sim. There's blue and black squares interfering with the flight planner window and the airport map window, and also the tach timer is jumping out of the C172' tachometer ?

Yes I have screenshots, updated Windows OS, latest Nvidia driver ( also tried rolling back to the previous with the same result ). I have well above the minimum required hardware.

Thank you both of you, I'll get the driver and use the Robin in the meantime then.

Glad to hear these are known issues so a fix is to be expected.
