Describe the bug
Rarely, on booting Raspberry Pi 5 with vc4-kms-v3d,composite and video=704x512i, the console displayed over Composite Video has the fields swapped (scrambled text).
Changing the video mode (e.g. using kmstest or labwc) fixes it. I have not observed the bug on a subsequent mode change; so far have only seen it on boot.
It's clearly related to (caused by?) #7010 but the problem seems to have appeared or become more prevalent since that was merged; perhaps in 6.18
Steps to reproduce the behaviour
config.txt:
vc4-kms-v3d,composite
cmdline.txt:
video=704x512i
Boot to text console on composite video. The field swap is intermittent and rare.
Device (s)
Raspberry Pi 5
System
a recent 6.18 (tbc)
Logs
nothing unusual or different between the swapped and unswapped cases
Additional context
No response
