DSO 2D10 Issue with higher memory depth

My brand new 2D10 shows a strange "interference signal" when the memory depth is set to more than 40k. The interference signal always appears with a time delay after increasing the memory depth and overlays the measurement signal. (Many, very short spikes on the screen) It also appears without any probes connected. Can I regard this behaviour as another bug or is there possibly a hardware defect?
I have already tested different software and Firmware versions. (At this moment, the actual Firmware from December 30. 2021 is installed, it doesn't help...)
Here a video of this issue.

Thank you for your feedback. This problem has been reported to the engineer, and I will notify you ...

I assume now that you are also assuming a firmware bug and not a hardware defect?

There is a new Firmware (dso3kb_20220118.upk) on official Website

This problem still persists...

One could almost get the impression that nobody is interested. I am well on the way to turning my back on Hantek for good. At any rate, you can't call that customer service. If a solution to the problem is still being sought, it would be desirable that it is at least communicated.
Return shipping to China is out of the question for cost reasons. Shipping from Germany costs about ?100, half the price of the device. In addition, you can read here from others who have tried it that there are sometimes problems with customs. Then the device and the money would be gone.
