Hi, I am working on an experiment that uses underscore letter replacement for self-paced reading and there seems to be a visual glitch with underscores in the bottom line of text. When running locally all the underscores are white and appear normally but when running the experiment through Pavlovia the underscores in the last line of the text are dark gray (image below). When the characters at the bottom line are not underscores (ie letters, periods, and commas) there is no issue and those characters appear normally.
I think this may be a bug, but if there are any solutions or workarounds I would really appreciate the help! Thank you! 
In this image next to the period on the last line the underscores are dark gray.
