I'm running Ubuntu 19.10. Whenever I unlock my computer after closing the lid some weird red and blue dots/lines show up on the unlock screen background. After unlocking, Visual Studio Code keeps the same pattern in some parts. It's usually only the terminal and everything I type there, but it can also affect the minimap too.
Reopening it solves the issue, but I'm quite annoyed by this little bug. My system is up to date and I haven't done any serious modification to it. The language/code I'm working on doesn't seem to be related as it has been happening for some time.
