ohhh wait, what the hell! Just rechecked the video doesn’t show it… it looks normal in the video… that’s not what I saw on screen… how the f.?
I will try to record it with mobile or something, give me a moment.

EDIT: this is super weird! When I check the video on my mobile, I DO see the lines, it looks normal. I just opened the video again on my desktop PC and here I can see the bug.... A1 until W26 (ish) ... the whole area just appears whtie for me... until I select it with the mouse. Can you check the video on a desktop to see what I mean?

I also just made another one with my mobile, trying to upload that one now as well.
Here you go, hope this one makes it more clear --> IMG_4385.MOV - Google Drive Can you see here now how the lines only become visible, once I select them with the mouse?
