I'm not sure how to describe this. Hope the video in the link helps.

In the video, I basically : 

1. Painted few strokes over the each other.
2. Repeated undoing the process&redoing the process with shortcut keys. 

OBSERVED RESULT
1- Some projections appear.
2- Sometimes pressing undo or redo doesn't do the job. It behaves as if the document was saved and opened again at a certain point in the process and the undo+redo data from the point is gone.

EXPECTED RESULT


SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION

It doesn't happen in 4.2.9.

Some 'projections' stays on the canvas when I make the layer invisible.

Yes I can confirm on my Linux build too, undo is severely broken on master. To me it seems to happen mostly on the last step you can undo, it fails to restore.

Bug 419372 speaks of a visual bug, but this is definitely not a repaint issue, the canvas content is messed up for me.
