-with no signal, the measurement bar is updating several times a second with nonsensical values
-the scope becomes very sluggish both in auto mode and pressing keys.
It takes almost a second to update after a V+ press,
pressing H+ gives a truncated trace for a second, only then refreshes.

Fixes:
1: The thickness of the waveform is reduced, making the waveform thinner and clearer.
2: The vertical lines of the square wave are brighter and more obvious

So just some further tweaks to the waveform display. Haven't tried it, but better than nothing, I guess.

Isn't "The thickness of the waveform is reduced" against the purpose o DPO scope? some day it will be a DSO  ;)

Anyway Fnirsi should give us an option to calibrate the device, it will be of much more interest

I upgrade it and on my unit only at 50mV/div there's some values updating. at 100mV/div no problems. No sluggish part on my unit after pressing auto and V+  or V- after, everything work fine. No probes connected. Will keep V40. Maybe some hardware thing with your unit? I bought mine in the end of Aug.

This bug not solved:

set FG to 1KHz Square Wave, 2 Vpp, 50% duty

press Auto

Press H+ until H=1us (top indicator) watch the glitch

Keep pressing H+ until H=5ns watch the amazing and wonderfull waveform  :palm:

Bellow 32KHz is useless, we can't trust anymore on the displayed image if we zoom in (not zoom button)

in my case this does not work, i can set to 0% but when I quit settings menu then no change, it always 100%, v30.
restore to factory settings does not help.

could be because of low value input ac/dc capacitor?
i've upgraded to v40, no sluggish noticed, they corrected menu with number of open measurements.
transparency still cannot be adjusted.
