After upgrading to Firefox 57 Quantum many website have rendering issues, such as empty frames, missing text or fonts, etc. I use Kubuntu 16.04 64 bit. So far, I've tried:
- Restarting Firefox in safe mode
- Disabling "hardware acceleration"
- Wiping out my profile
- Purging Firefox and reinstalling
- Running Firefox from a clean user account
But nothing helped so far.
Any tips on how to solve this are much appreciated
