red progress line disappears on some zoom levels.

[themusicgod1]

After editing the following project for awhile, on some zooms(Basically anything lower than 12) the red line disappears. I can play the video, and it acts as if it's still there, keeping position in some place, but there is no red line displayed in the bottom portion of the window.

Zooming out allows you to see roughly where you are...but if you want to get some scene cut in the right place it's kind of hard to get your timing right when you can't see what you're doing with the red progress line.

(Also, it seems like when you zoom in you can only see the top 3 tracks, but I'm not sure if this is a feature or not.)

2 screenshots attached, 1 with and 1 without at different zoom levels.

New projects are not affected, but if I can close openshot, open the .osp project file in question that causes this, the red line goes missing again. .osp project attached.
