Moving explorator's middle bar creates visual glitches

[mateuszbasiak]

Together with @JKolodziejczyk and @apospieszny, we have been testing NanaZip as the final project for the Software Testing course at Jagiellonian University. Here is one of our results:

When moving the middle bar of the explorer the view glitches - the second view isn't shown and the bar itself disappears.

Reproduction steps:

1. Turn on the 2 panels view
2. Click the middle bar and move it quickly to the left and right

Expected result: the view gets shortened/widened without any glitches

Real result:

Used version: NanaZip 1.0
