I just tried to run a project with provided jmods and at some point,
certain nodes are just not rendered anymore and the window contents
vanish. But they render for a short period of time.
There is no exception thrown as far as I can see, so not sure what you
need for debugging.
For testing, this is the built application with the d3d12 jmods that you
can use to attempt to reproduce the problem: https://we.tl/t-DJuX0BeqXm
. It is built from these sources: https://github.com/xpipe-io/kickstartfx

Hello openjfx-dev,
The second Early Access(EA) build of JavaFX with the Windows Direct3D
12 rendering pipeline is now available at:
https://jdk.java.net/javafxdirect3d12/
Please test this bundle and share your feedback by:
- emailing [email protected] or
- reporting issues via JBS[https://bugs.openjdk.org/] or at
https://bugreport.java.com
This is the second EA release. The backend is feature-complete and
went through a first optimization pass, but it still requires some
more testing on more hardware variants before we can consider it
complete. As such, with this release we also would like to call for
help with performance testing the backend (more details on that will
be sent in a separate email thread).
Known issues and pending tasks are captured on JBS and can be accessed
using the filter provided on the Direct3D 12 EA page
[https://jdk.java.net/javafxdirect3d12/]. Before reporting a new bug,
please review the existing issues to avoid duplicates.
Important Notes:
1. This is a Windows-specific feature, so only a Windows-specific
bundle is provided.
2. The default rendering pipeline is set to d3d12. Use
"-Dprism.order=d3d" or "-Dprism.order=sw" to select one of the other
pipelines for comparison testing.
3. It is recommended to use JDK 25 or later.
4. At this stage D3D12 backend is feature-complete and went through
the first phase of optimization. It is worth noting that, while
generally we noticed performance improvements, it might not be on par
with D3D backend on every machine combo - we already noted
performance being worse on recent NVidia discrete GPUs
[https://bugs.openjdk.org/browse/JDK-8370486] and are looking for
solutions.
5. Issue behavior may vary across different hardware, so please
provide detailed information, such as the output of "java
-Dprism.verbose=true" or used hardware, when reporting or discussing
issues.
6. Refer: Run HelloWorld using JavaFX SDK

We look forward to your feedback.
