View side/side under/over switch

[romills]

If you switch from view side by side to under over, then back to side by side. you lose the right hand file. This reappears if you resize the window (sometimes it doesn't reappear or it just takes time to reappear after resize)..

It also disappears doing over under to side by side and back to over under.

Comparison done on text file.

Thanks for the report. I'll open a tracker entry to get this fixed.
