JavaFX Content Rendering & Resizing and Font Bugs In Linux

Seeing as how this important issue is seemingly being ignored, I've
decided to upload a video showcases the bugs. If this isn't evidence
that there is a problem with JavaFX's content rendering, resizing, and
fonts I don't know what is.
The issues I'm experiencing affect every single JavaFX application that
I've tested, which is:
Goliath Envious FX(mine, repo linked earlier)
Of special note is Scenic View. For reasons I don't understand, Scenic
View does not always show the glitching. It, however, has extremely
laggy resizing. Even when it isn't glitching however, it is always
possible to make it happen by going to Help > About and closing the
About window that pops up.
Node count for my app is 422 at most and about 150 at its lowest. This
number will increase/decrease with the amount of Nvidia GPUs connected
to the system. That decreases or increases depending on the content
being shown. I have no idea where or how it is even that high seeing as
how hardly anything is even on the screen to begin with.
Font boldness bug can be found at 6-8 second range in the video. It used
to happen in a different part of the GUI...
Can we please actually talk about what the actual issues are instead of
blaming the end programmers and/or excuses like "it's just too complex"?
Side note 1: to whoever is developing Scenic View(assuming they are
subscribed to this list), your application spits out errors like
crazy(see the video). java.instrument was exported in module-info yet it
threw errors saying otherwise. Application output was throwing
connection refused exceptions left and right. Some X related code was
spitting out a colored error message saying java was doing something
networking(?) related that it shouldn't and "please stop that" or other.
I didn't copy the exact text sadly.
Also, specify a min width/height.
Side note 2: I was wrong about JavaFX not supporting 1440p and 4k. It
uses GDK_SCALE to scale the UI. Problem is, GDK_SCALE isn't a reliable
way of getting the actual UI scale and will only work for native
displays at native resolutions. Using xrandr to scale the output display
results in 1x scaling even though the DE is being rendered in 4k. I'm
guessing this is related to having to log back out and log back in in
Windows. It would be nice if JavaFX had failsafe code to dynamically
