Memory leaks on Linux with hardware renderer

[Itai]

Thank you. Having gotten no reply, and seeing the bug report was closed and
with not means of commenting in the bug report system, I have since (about
an hour ago) filed a more detailed report (JI-9042009). I believe they
could be safely merged, but the second one does contain some more info.
