System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: Intel(R) HD Graphics 4600 Intel 4.3.0 - Build 20.19.15.5171

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-08-01 18:52, hash: 836aeebf70
Worked: 2.93

Short description of error
When forcing to draw more lines by changing the FPS and base, the point where all vertical lines overlap makes disappear these lines and the scrubbing bar (not the cursor).

Exact steps for others to reproduce the error

Open a Video Sequencer panel (Sequencer)
Set FPS to 1 and base to 10 (In Properties/Scene/Dimensions/Frame Rate/Custom
Zoom out

Observations:

Of course the disappearing of the scrub bar may be fixed, behaving like 2.93.
On the other hand, the drawing of vertical lines keeps being "arbitrary" in the eyes of the times being displayed. For example, comparing 10 FPS and 5 FPS (base 1) max zoomed out, when using 10 there's 1 line inbetween the others that match with time displayed (I'll call them main lines). When using 5, it's 3. The problem scalates when using more extreme values, causing the lines to overlap.
Another way to trigger this issue is by changing the Resolution Scale in Preferences, where more lines will appear inbetween the main ones, the larger the UI is. Being this the case, with the UI at 2x the bug described in this report occurs with 1 FPS and base 5 instead of 10.
From the user point of view, I'd suggest to display up to 3 vertical lines inbetween main lines. At least for me, I loose track of the actual value of the inbetweeners by having 4 or more, aside it becomes crammed.

I can reproduce the issue, but strangely it dissappears when showing frame numbers instead of time. This is the case in all editors not only VSE.

In VSE I have resorted in using hack, which multiplies line spacing by 3 so lines aren't too dense. But they still result in size steps of 1, 2, 4, 5, 10, 20, etc.

From the user point of view, I'd suggest to display up to 3 vertical lines inbetween main lines. At least for me, I loose track of the actual value of the inbetweeners by having 4 or more, aside it becomes crammed.

Can you explain this in more detail? Do you mean to add more lines?

I think main problem is fix when labels do overlap only every other is displayed but when you increase spacing by 3x, it is rather unpleasant to work with. So I may revert this change or at least make it even.

Sure. What I mean is that the number of lines being drawn should be consistent regardless of any combination of FPS, base and/or UI scaling, since it's pointless to have more lines if you can't know what it represents and/or makes it crammed.

For example, using FPS=2 and Base=1:

Zooming out until 30:00 works as spected: drawing and removing new lines.
From this point on, no more lines are being removed.

What I meant by showing up to 3 inbetween lines is that it becomes crammed after that, but I guess the main issue is that the hour lines are not being removed.
