I've done it occasionally as well, usually when it
seemed unavoidable, 'without problems' (the
inverted commas are meant to indicate - but
not with images in a list cell renderer, and not
that I have been able to test on Mac. - no Mac.
available)

I think the problem comes up mostly when a
'lightwieght' tooltip or menu might appear above
or 'over the top of' a heavyweight component.

AFAIU, it does not impact lightweight 'root level'
components such as JFrame, JOptionPane or
JDialog - they can appear over the top of AWT
components in other root level containers without
problem.

OTOH - the OP's mixing of Swing and AWT seems
unnecessary in this code example, and would be
the first thing I'd look into (i.e. change).

Exactly why that would cause the flickering the
OP reported, I cannot say.  (So I do not hold a
*high* confidence that changing the Canvas to a
(e.g.) JPanel will solve the problem.)
