GNOME Shell doesn't have a source file of that name. From
codesearch.debian.net, it looks like this is most likely to be coming from
chromium (or perhaps Google Chrome or an Electron app) or qtwebengine. It
might be a bug in whichever chromium-derived renderer is in use, or a bug
in your GLES2 graphics driver.

Do you use chromium, Chrome, Electron or qtwebengine?

Recent versions of GNOME Shell are meant to give each launched app its own
connection to the systemd journal so that log messages are correctly
attributed to the app, but apparently that isn't working here and the
messages end up output to a logging file descriptor that is inherited from
GNOME Shell. How do you launch the chromium-based app?
