Tabular-float + scrolling

[R. Lahaye]

Hi,

When the cursor is inside a table of a tabular float,
the "tab"-label and the float-border-lines disappear
while scrolling.

PS: Is there a connection with other scrolling problems:
   -> black vertical lines appear while scrolling
   -> context of canvas jumps when resizing the lyx window
      after a (long) scroll
