Seeing as how this important issue is seemingly being ignored, I've decided to upload a video showcases the bugs[1]. If this isn't evidence that there is a problem with JavaFX's content rendering, resizing, and fonts I don't know what is.
Your video looks similar to a bug I first encountered two years ago [1]. I was reluctant to reply earlier because I can't reproduce the bug in a windowed environment. So far I have seen the problem in the two cases listed below (the bug report lists only the first case):
(a) on a Monocle platform using an off-screen composition buffer that is allocated as a non-direct byte buffer, and
(b) on a Monocle platform using the frame buffer directly as the composition buffer, and its horizontal visible resolution differs from its virtual resolution.
If I play your videos at the slowest speed, I see the entire frame jump up when you resize its window. That is just what you would expect if the position of the buffer was reset to zero while the buffer was being used to draw the frame.
Our environments are very different, and your problem may have origins outside of JavaFX entirely, but it may still be worth trying the same debugging technique described in the bug report.
