Description
Some scenes in Kang Fu (using high-resolution mode) exhibit image distortion.
For example, the GREED logo scene and the title screen.
The most noticeable issue is the distortion of displayed text strings.
Line Mode is set to Auto.
I tried both options for Remove Interlace Artifacts, but there was no change.
Remove Interlace Artifacts=Disable
Remove Interlace Artifacts=Enable
For reference, I've attached a screenshot of the same scene captured in WinUAE 6.0.1.
(Line Mode is Double, Interlaced Line Mode is Double Field)
The display on the actual hardware is similar to how it appears in WinUAE.
Is a fix possible?

Research direction
Reproduce the Kang Fu high-resolution scenes, especially the GREED logo and title screen, using the reported Line Mode and Remove Interlace Artifacts settings. Compare the output with the attached WinUAE and hardware references, then trace the high-resolution display-rendering path; done means the displayed text and images no longer show the reported distortion.
