[Bug] Exception in thread "JavaFX Application Thread"

[RequestPrivacy]

While browsing the log files for #696 I noticed following stack trace which casually dumped 300.000 lines of log output during roughly 2-3h:

Sparrow had stopped mixing but seemed otherwise okay...after some back and forth switching between Sparrows and Github and other clients Sparrows interface went white on me and I had to close it via the window managers close button.

Still on Kubuntu 22.04 LTS running Sparrow 1.6.6

Unfortunately this is entirely a JavaFX framework issue (no Sparrow code in that stacktrace) so we'll have to hope for a fix upstream.
