Great! What would be very useful as a starting point is a manual ming
testcase so that the behaviour can be verified visually: several
static / dynamic TextFields variously with embedded and device fonts,
and with various rgba values for the text and the parent MovieClip. If
there is a description of what it should look like, it is at least
helpful for fixing the bug even if it doesn't stop regressions so
easily.

The fix is possibly in TextRecord::displayRecords() - when it's a device
font, using cxform() instead of get_world_cxform() and always setting
alpha to opaque. TextField::get_world_cxform() also affects border and
background colour of TextFields, so it would also be worth testing
whether these are affected by the parent's transform or not.
