--- Comment #8 from Rémi Bernon rbernon@codeweavers.com --- Thank you! It looks like the strings returned by glGetString get invalidated even (probably because of a GL context change) though the documentation says that they are supposed to be static.
https://gitlab.winehq.org/wine/wine/-/merge_requests/9491 should fix the issue.
