(This image is a screenshot of the original, as the original was too large to upload.)
As far as I can tell this is random (ish), when it happens, it happens continually, at least for several minutes. It only happens on “std” setting, not on “hdr” or the others, but switching back to “std” stilll causes this error.
The image above was taken yesterday, I have about 10 other similar ones. It also happen the day before. But today I can not get it to reproduce the problem.
I have already had lots of issues with the open camera provided by /e/, such as green tinted hdr pictures or random crashes.
What may sound strange but actually works is just to use the original open camera app which may be found on f-droid and source forge (for those interested it’s here). Since i have used this method, i’ve never had problems. It’s the exact same software with a different UI.
