only Ubuntu 18.04LTS SIGSEGV witch libjfxwebkit.so

[SteepPepper]

JVM (openjdk-11) crashes only in ubuntu 18.04. It happens when rendering webengine (openjfx11) page containing media data (animation, sounds, mp4 video). One or more times the rendering is successful, but when refreshing the page always and constantly the virtual machine crashes. I checked with different builds of jdk/jre - same result. But in the new ubuntu (20.04) the same java code works without SIGSEGV. This error is only in ubunte18.04
