Description teancum144 2015-06-29 20:32:09 UTC 
I took a snapshot of the same text three times using .jpeg, .png, and .webp. Only the .webp is illegible. I also reported this to the webp issue tracker and they referred me here. Here is a link to that bug report, which includes attached sample screenshots:

Avoid quality being set to 0 and use default of 75

For some reason, set quality was called with -1, which was limited
to 0, the lowest quality.
Instead now, if a value < 0 is given, we still use the default of 75
