Comment 16 for bug 1818770

I'm using stable/rocky.

If you try to read the png on stable/rocky [0] or master [1] you will notice that there are errors. I just checked for stable/queens [2] and that looks correct.

So your fix might be right but it seems that we also need to fix the png for rocky and master.
