If a project contains a very large number of tracks (several hundred), the tracks have strange horizontal bars running through them.

I've only tested on Linux.

WORKS FOR ME on Windows, accordingly RepeatableAll -> Repeatable.

These bars are extra unwanted bars between tracks, not the bars between channels in a stereo track, as the top dark edge is two pixels high.

Is this a regression?  That would help determine if it is the refactoring changes which have caused it.

Works for me on W10 and macOS 10.14.5 with latest alphas

Tested with 512 mono " min 45 sec tracks on both platforms

(In reply to Peter Sampson from comment #2)
And went back ad restested on both Mac & Win with 512 stereo tracks - still WORKSFORME

Comment 4 Steve Daulton 2019-07-29 07:45:30 UTC

I'm no longer seeing this problem with the current 2.3.3 alpha, so it looks like something has fixed it. Closing as WORKSFORME.
