I'm running into an issue with wgpu_glyph where it renders gibberish letters if an OpenGL or ANGLE backend is used. But if a Metal backend is used everything renders perfectly normally. Unfortunately Chrome does not yet support Metal unless enabled in an experimental feature flag. See images below

One thing to note is that the gibberish letters are different every time a new window is opened. But are not different within the same window. This is not the case with Firefox where the gibberish is different every time. It does work without changing any feature flags in Safari. But that is because Safari Uses Metal by default. This issue also happens with Firefox (113.0) .
