Status: RESOLVED DUPLICATE of bug 1666160

(Core :: Graphics: Text, defect)

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

1. Visit/create a repl at https://replit.com/
2. If you're visiting a repl, make sure it's one you have edit permissions for
3. Wait for the interface to load
4. Look at the terminal panel for running commands

Actual results:

There's just these... rainbow vertical stripes.

I've seen this happen on other sites, but I've had trouble pinning down what was the common thing about them that kept triggering the behavior. Starting firefox in safe mode does not resolve this issue, so I think it's something rendering related.

Expected results:

Being able to see the terminal panel and actually read it.

Same graphical glitch occurring with GeeTest captchas, rendering them almost unusable.
