Memory leaks on Linux with hardware renderer

I'm experiencing multiple memory leaks with JavaFX on Linux, to the point
where I'm not sure which bug to report, as it seems like a systematic

The memory leak seems to be completely absent when using the software
renderer (-Dprism.order=sw), and does not seem to happen on Windows
(presumably not on Mac either, although I have no Mac to test it).

Test cases include:

1. Use ProgressIndicator with progress set to Indeterminate - with default
(HW) renderer memory consumption quickly rises, climbing to 8GB and more if
not killed. With software renderer memory usage is reasonable.
2. Using Scene Builder - after a few minutes with Scene Builder it quickly
gobbles up all system memory - again, problem seems to go away if using
software renderer. This test is less repeatable, as some actions seem more
detrimental than others.
3. Using Transitions on nodes (See attached code "". I have filed
a bug report about this issue, JI-9041860). Running with default renderer
the simple program reaches 3GB within 30 seconds, and memory continues to
climb. On software renderer memory consumption remains <100MB for a minute
and more.

As I said, I am no longer sure it is prudent to report specific bugs, as
this seems to be some low-level problem. I just want to know if this is a
known issue and if there is any way to get around it (besides using the
software pipe, which obviously has it's own disadvantages).

For reference, I'm using Debian (testing, updated today), kernel version
4.6.2, Intel HD4000 GPU, Intel driver version 2.99.917 (kms driver),
OpenJDK version 1.8.0_91-8u91-b14-3-b14 (behavior is identical on Oracle

If there is any other information needed please let me know. If this is a
known issue I apologize, but I have tried searching and didn't find any
reports of such behavior.

Thank you.
