Yes. 10x is the typical rule of thumb in instrumentation. Its in shape at 5x, its very good at 10x, and its very crisp at 20x. The more harmonics the system is able to catch the sharper a square is displayed.
Below, you can see how much changing the shape of waves on the oscilloscope screen when i am turning the trimmer of the Kwak Clock left and right directions.

I turned the Kwak clock trimmer to arrange the square wave shape. Is it looking okay? What i am understanding is, for the proper square wave, top and bottom horizontal parts of the wave should be in equal length. Any comment?

P.S. 50 Ohm scope termination or other specified, plays a crucial role depending on the source's output impedance so to see square shapes in their real nature at point of probing. Maybe an RG 58 with naked tip and short shield to probe signal & near GND, also a 50 Ohm across at the BNC end.
I found this on the web :

It's showing me how should be the Kwak clock waveform.
Shown waveform is same with mine. Even mine is smoother 🙂

As Salas advised (and mentionned in KC7 notice too), we should better use a 50Ohm high bandwith probe to see real square.
I'm on the way to build one, However here is what i have with a classic probe.
