DSO 2D10 Issue with higher memory depth

Unfortunately I have the same issue on my 2D10 I received just a couple of days ago from Banggood.
Displaying signal at 4k and 40k points works OK, but when I go higher in memory settings, the scope starts behaving badly.
Memory settings 400k, 4M and 8M are unusable.
This happens almost instantly when I change the Volts/div setting, zooming in on the signal.
If I switch it OFF and ON again, the problem comes back by adjusting V/div.
The problem exist also in GND coupled mode or even the probe disconnected with no signal at all.
Serial: CN21350290127xx
SW: 20210726
HW: 3.2.1.0.0.0.0.1
FW: 3202
I have since tried the latest SW from the Hantek site 20211230, it behaves the same.
I hope Hantek will reply, I'd like to know if it is a hardware or software defect and can we expect a fix?
My video of the problem is available here:

Looks like there is no solution to this issue.
The only feedback we received is that the problem has been reported to the engineer.
Shall I return my scope and ask for refund?

Just a quick feedback from me, the received FW upgrade fpga3203 solved the issue for me, I have not experienced the signal spikes any more.
I have also shared the package on the corresponding EEVBLOG forum page.
