Screen recording illustrating the problem

Resize handlers does not appear when moving mouse over the edges connecting view panels. There is no way to resize view panel which makes it very hard to use since the only other option to make it bigger is to maximize it. After clicking on the edge connecting views the view automatically resizes to some random size (sometimes smaller sometimes bigger). For example clicking on the edge of Project View made it smaller. But clicking on the edge between editor and Data Source Explorer in the bottom panel made the bottom panel enormously big. In the attachment you can find a short recording illustrating the problem.

Important! I can reproduce this only on my Ubuntu 16. On another PC where I have Ubuntu 18, it is working correctly.

Regression:

In Eclipse IDE 4.17 this does NOT work correctly.
In Eclipse IDE 4.16 this does NOT work correctly.
In Eclipse IDE 4.15 this does works correctly.
