The site works as long as you don't need to log in.
Once you're logged in it also works perfectly (I know because I didn't encounter this until I accidentally logged off...)
The only part of the site that doesn't want to work is the login page.
I have tried with my normal setup, using the safe mode and with a fresh profile, the issue remains.

This is what appears on the console, on the page what you'll see is the login prompt, where if you try typing anything in, or even pasting something there, it will show up as blank characters of a smaller font.
Even if you type the right credentials in, the server must be receiving those weird blank characters instead.
The console mentions WebGL being disabled, but after checking about:config I found the following webgl related options (among others of which the relevance I wouldn't know):

Code: Select all

webgl.enable-webgl2;true
webgl.disabled;false
webgl.disable-wgl;false
It doesn't look (to me, the inexperienced user) like it is.
I tried loading the page again after setting the following, which defaults to false to:

Code: Select all

webgl.force-enabled;true
With no change.

If there is more info I can give to help identify and solve the issue I'm open for requests.
