--- Comment #5 from Liam Martens <hi at liammartens.com> ---
So after doing some research on this topic it appears to be caused by the hardware acceleration policy. By default this is "ON_DEMAND" which causes the transparency to fail at times (it also fails when applying animation transforms for example). However when changing the hardware acceleration to either NEVER or ALWAYS the transparency works as expected.
