I don't see how you could see "awful deinterlace-style lines through the
Myth GUI" provided the GUI is never interlaced to start with...
The GUI has barely any animated content, don't see how 50Hz would be any
different the 60Hz... I'm afraid the issue isn't on your computer

I don't know what else to say, except that I am seeing what I am seeing.

I only have 3 modelines in my xorg, 1080p at 60, 1080p at 50, and 1080p at 24. These
will actually refresh correctly for 59.94 and 23.97 rates too. If the
display receives any signal that does not fit these refresh rates, it
defaults to 1080i at 50Hz, which is what I am seeing until I play the first
recording or close Myth.

I understand that no part of the GUI is interlaced, but from that update
onwards as Mythfrontend is initially opened my display does not seem to
interpret the signal as any recognised refresh rate and so changes to
1080i. This results in jagged lines on every application displayed my pc,
including the desktop if I minimise Myth. But I know it is not being sent
from the pc that way, because a screen capture taken at this time and
viewed once Myth is closed appears normal (as does everything once Myth is
closed or a recording is played).
