List of steps to reproduce (step by step, including full links if applicable):
- Go to for example https://commons.wikimedia.org/wiki/File:Shc_logo_ppt_rgb_urlogo_freigestellt.gif or https://commons.wikimedia.org/wiki/File:Lexlogo.gif
What happens?:
The generated thumbnail looks fine but down at the file history section where there is a smaller version it looks awful, the foreground is all messed up. On the first the text "Stolle & Heinz Consultants" is unrecognizable and one of the three lines is not rendered. On the second the text to the right is all gone.
What should have happened instead?:
It should look fine both on top and in the file history section. The text should be possible to be read and there should be three lines, not two.
Other information:
There are also more examples at https://en.wikipedia.org/wiki/User:Jonteemil/sandbox3#GIF_files_that_look_bad_in_file_history. It seems that this very problem already had a task, T15252, but it was closed a decade ago as resolved. Evidently the fix they came up with has been undone in the meantime.
