Best practice for "unexpected white balance coefficients" in darktable

Should I reduce the dimensions on export?

[Friendly reminder] Limit JPEGs to maybe full HD resolution

We had multiple cases where people thought it was a good idea to upload full size jpegs for posts, which gives us 8-23MB! jpeg files. I think for most discussions it is more than enough to limit our self to 1920x1080 or smaller resolution. This does not apply to raw files of course. Also it might also help to not use the “upload file” function for image files. just drag’n’drop them into the post. Thank you in advance

And, when exporting, a quality setting of 85 - 95% is good enough. 100% blows up the file size, without actually being lossless.
