A bug? You can't really classify a slower or faster waveform update rate as a bug - since almost ANYTHING (input levels, frequency, measurements on/off, etc) can affect the rate. Rigol has clearly done some tweaking in this FW version to provide better-balanced rates across the smaller time base settings than the DSO used to have. If the cost of getting > 10k wfrm/s @ 20ns/div for two channels means that setting needs to drop, it's fine by me.

It is quite likely that is a new bug. But they release a new Firmware again since a long time. After many new devices offers maybe they have more time to release new fixes....  ;)

Read my message above. It's not realistic to classify slower or faster wfrm/s rates as bugs. Is it a bug when you turn on High Res and the rate drops? They've added a new working time base to the new firmware (1ns/div) and the rates have shifted. Nope - not a bug.
