When dragging for resize geometry or main window, window flashes

[tkbd]

This problem occurs in v2.1.4.x
Compared behavor of Wings3D 2.1.3 and Wings3D 2.1.4.1 for this problem.
As a simple example, divide horizontaly main window by two parts,Geometry is upper, Log windows is below.

In 2.1.3 this is OK
As move the separator up and down, the geometry content of v 2.1.3 scales smoothly according to the height of the window.
Also,Drag the lower right corner of the window to change the size of the entire window.
The contents of Geometry is temporarily become keep filled while dragging for resize white.
This is not a problem.

But,In 2.1.4.1 is NG
As move the separator up and down,The content of geometry window flickers violently.
Also,Drag the lower right corner of the window ,it more blinks white appears.

This problem occurs when the Geometry/Mainwindow size is dynamically changed.
Intense flashing would be bad for eyes a bit...

It seems to be something related to the video card capability/driver.
I can't observe that here except a little lag with these 2K objects:

This happens even if there is nothing or one object in the geometry.
I took screencasts for both applications behaviour.

I just want to know if this problem is still present in the current version.

I just want to know if this problem is still present in the current version.

At first,I will talking about current MacOS environment.
There were also several updates on OSX 10.11.6 later(but no change version number).
For example Some changes have been made to Intel's drivers by Apple's Security Updates.
But I don't know whether it brought to good affect to this problem.

Based on them,
The flicker when moving the vertical frame bar was reduced apparently!
( Flickers were reduced as amount same as when horizontal bar moving for up and down.)

And, when window size changed that it still occured flicker.
But It wasn't also as intense than screen capture recorded before.

I think that a slightly better impression than before.

OSX 10.11.6 + Some updates
Wings3D 2.1.5

I'm going to put this 'bug' in standby, since it seems to be related to graphic driver issues.

In my PC I cannot reproduce this behaviour even setting the Wings3D's window to a QHD resolution (2560x1440px)
