"White" rendering in IR after undo

Corona Corona for Cinema 4D Issues

Win 10, latest Beta 2 from April 19, C4D R19.053

If I change the content of a channel and want to “undo” it, the IR renders “white” until I restart it.

Still happening. Not fixed for IR.

Gonna check more old reports later ^^

Thanks Mike, It seems it’s still the case in RC4 too. It’s now on my list.
