Short description of error
When enabling Multiframe editing it doesn't reliably update the lines.
In this example I didn't originally select all keyframes. If I do so afterwards, the viewport doesn't update immediately but only after I navigate the viewport.
Note that the lines also briefly flickered in the onion skinning colors.
If the view is in Front Orthographic, the lines can also have difficulties drawing on top of the grid overlay.
That's another way of reproducing the flickering when updating the viewport.
Exact steps for others to reproduce the error
Also try switching the current frame and see how the lines flicker.

Could you test if this only happens when you use
Select All
or Unselect All? I mean, if you select the keyframes with the mouse in dopesheet works?Added subscriber: @amelief
@amelief dout think this can be a missing update?
Select all or deselect all doesn't update the Multiframe drawing when I do it in the dopesheet, but it does when I do it in the viewport.
And yes, if I select keyframes with the mouse in the dopesheet it does properly update the viewport.

Yes, I think there's a missing update in some of the selection operators. Hopefully, it should not be hard to fix.
Quickly going through each of them, it seems to be working for click-based selection and unselection, but not for select all/box/circle/lasso.
