Render not working well. Got black case.

[henres]

Hello,
Tried to render at 4 and 7 but got black case at some part.

Here the exported image (I scaled it down for github issue)

I tried on vivaldi, firefox and chrome on manjaro

Thanks

adding my experience : sometimes the render will give bad picture, it seems like its hurrying, trying to render too fast and it will take a picture half way between the movements it makes ( ???? ) (vivaldi and firefox)

could there be a checkbox like "force take your time"
its like its rushing and making bad render
when it messes up the window moves really fast and blinks white

ohhh its because i render once in an area and it like saved a wider area nearby? and so when i render again nearby it wants to just do it really quick .. which makes it mess up..

cause i was keep having this error in a region .. and then iam like ok ill go totally different 500 miles away and then it works really slow like you'd expect it

so like, it needs a little delay before moving the view i guess .. the view like moves too fast for the screenshotting thingy

..oh .. my issue might be different than henres .. or maybe related idk sry
