In Ubuntu 24.04, window (such as Sandbox) are displayed with a width of 1px.

In Ubuntu 24.04, when I click the Sandbox button, a window appears with a width of 1px.
The white area in the upper left of this capture is the Sandbox window.

This seems to be a bug in JavaFX (OpenJFX), and it works fine with version 22 or later.
(Is this bug perhaps JDK-8316423?)

jitwatch/ui/pom.xml

Line 17 in 8234257

<openjfx.version>19.0.2.1</openjfx.version> <!-- https://mvnrepository.com/artifact/org.openjfx/javafx -->

        <properties>
-               <openjfx.version>19.0.2.1</openjfx.version> <!-- https://mvnrepository.com/artifact/org.openjfx/javafx -->
+               <openjfx.version>22</openjfx.version> <!-- https://mvnrepository.com/artifact/org.openjfx/javafx -->
        </properties>

NOTE: JavaFX 22 requires JDK 17 or later.

Hi @YujiSoftware thanks for the report.

I've read the JBS bug and it seems to occur under a specific combination of OS and window manager.

I'm afraid I don't think it justifies changing the requirements for JITWatch from JDK8 up to JDK17 but I will see if I can mitigate it by resizing the stage after it has opened.

Kind regards,

Chris

Seeing this under Debian 13.1 as well, with 03c2796 . The above fix also resolved the issue for me.
