eon m problems with dual iso, bad pixel

[hanbs0814]

I'm using latest crop mood with my eos m, and there are some problem with my footage.

when I shoot the sun in dual iso mode, it has some line in the light spot after dual iso process.

and when I shoot the white wall, there are some dots on the wall. It's somehow invisible, but it becomes vivid after grading.





Can I fix it from MLV app?

Additionally, Can I make the preview clear when I use dual iso mode?
