Mysterious lines on selected waveform :)

[Kostas_Grigoreas]

Hi! On specific horizontal zoom “steps”, lines appear on selected waveform.

Just curious if they are of any use… I send a screen shot.
Thanks

Looks like a bug. But what is causing this? What could be the special case?
Is this something you often see?

I will test it on different computers and let you know soon.
Thanks

Never seen those on a MAC or PC running WL9 or WL10. FWIW

Hi PG!
I send you screenshots of random zoom levels, where the bug appears. (Not really a problem for me though )
I also send some tech info of the computer (Lenovo laptop, AMD Radeon ™ R5 M330 + Intel(R) HD Graphics 520 [Display adapters).
Thanks
