Artifacts

[welshi32]

Hello. With my new dev board i've seen some HORRIBLE artifacting
15MHz

20MHz

Does someone know how to fix this or is this permanent?

due to the popularity of esp modules there are lots of cheap knockoffs of variable quality

UPDATE: For some reason, on the default webserver code the lines are gone. on 20MHz there's still some of the block artifacts but on 15 it's fine.

Image fron default webserver code

I genuinely have no idea why this is. Witchcraft or what.

My hypothesis: This webserver is heavier, making the 3.3V rail sag and in turn making the other rails that camera uses sag, resulting in these lines

The lines dissapear but the colors are screwed up

[s60sc]

no, AF only

I fixed it. Apparently the default example has gain ceiling raised. If i lower gain ceiling on it, the lines appear. Here's to hope someone in the future that has this issue comes across this thread

Adjusted gain ceiling, but the stream is laggy for some reason now
