You do not know also my GWINSTEK GDS-2072E, as i already said, it updates screen during vertical trace positioning, and it is a toy, so no need to mention expensive DSOs like Lecroy or Keysight.
What i saw in Steve video is an utterly frozen trace dragged on the screen, AFAIK this happens also with the 5K euro HDO4804 :--

I have a toy Keysight EDUX1052A and it updates screen during vertical trace positioning. I think the issue is not that it is useful or not for the scope to update the screen during repositioning of traces, but it shows how the SW is working inside and synchronizing all its modules concurrently. The fact that some operations need to be frozen, means concurrency is not correctly implemented and taking advantage of the powerful CPU cores and it's communication with the FPGA and it also causes freezing and application reloads. It is my humble opinion, as a software engineer.

That's exactly the point.

Signing this.
What benefits you got when it´s not "freezing" while playing with the vertical adjustment..

Then all scopes I know have this bug.

Not the Keysight. It updates the waveform during vertical positioning

Keysight 2K stop when do vertical positioning.

But that is exactly the point. Toy scope that has special architecture with minimum memory (it has 100-200X less memory than HDO1000), measurement from decimated data and no statistics. It's architecture was optimized for CRT scope emulation and fast as possible UI at the cost of everything else..
But I do think all of these news scopes could use some optimization. It can freeze waveform while I move knob. It shouldn't wait for a second to resume though. That is the key. Keysight 3000T that also stops triggering while moving button, resumes triggering immediately, so most people think it keeps displaying while moving.
