      Description

      ADDITIONAL SYSTEM INFORMATION :
      Debian Linux 10, OpenJDK 11.0.5

      A DESCRIPTION OF THE PROBLEM :
      Pasting an emoji such as U+1F4A5 ("💥") into a JavaFX TextField or displaying it in a Label causes various combinations of freezing and graphics corruption.

      This has so far only been observed on Linux (various distributions: Arch, Debian, Fedora) in Java versions ranging from 11 to 14.

      Prior discussion: https://github.com/javafxports/openjdk-jfx/issues/287

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Launch a JavaFX application that contains a TextField
      2. Paste an emoji such as 💥 into the text field

      (Alternative: Launch a JavaFX application with a Label that contains that character.)

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Emoji displays as a character, with or without color (I'm not picky)
      ACTUAL -
      The application either freezes entirely, or displays various graphics glitches, including blacking out or copying and vertical inversion of Nodes.

      The application also emits a number of stack traces like this (middle trimmed):
