Semi-crashes Desktop on Kubuntu Linux 20.04.4
kah-ell opened this issue · comments
When started, it takes tens of seconds, almost a minute, to show a window. On a 3960X 24-core Threadripper with 64G RAM and Nvidia 2070 SUPER.
This window, however, is unresponsive to clicks. I managed to get one right-click out of it among several tries (and showing a context menu), but it usually only started to seize the mouse for the whole desktop. After trying to start it from the command-line, this is printed out:
Sep 09, 2022 4:40:07 PM com.sun.javafx.application.PlatformImpl startup
WARNING: Unsupported JavaFX configuration: classes were loaded from 'unnamed module @2dd61f5b'
(JDKMon:815907): Gdk-WARNING **: 16:40:26.926: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.
Ctrl-C wasn't working in the terminal and no mouse input was possible anymore. One pkill later the window died, leaving an "empty" window shell behind, including a defunct systemtray icon. Still no mouse on the whole desktop. After switching to console (away from GUI Desktop altogether), a kill -9 finally ended the misery.
The window that showed up did look pretty, though. Quite a pleasant surprise.
It seems to come with it's own Java runtime, right? Haven't tried to run it with one of the installed, known good ones though.
I was thinking about using JavaFX for internal GUI projects, but yeah, that was a kind of cold shower right there and then. Yet I still like the looks of JDKMon. ;)
Hmm…interesting. It runs fine on two of my ubuntu machines.
