I'm currently seeing a similar issue on Firefox 71.0 with HD 5000. Google calendar doesn't trigger it, for me the act of switching tabs can trigger it. And if I don't switch out of the "glitchy" tab it can even trigger a reboot.

Firefox 71.0
Mojave/10.14.6
MacBook Pro (Retina, 13-inch, Late 2013) (MacBookPro11,1)
Intel Core i5 / 2.6 GHz
Memory: 16 GB
Intel HD Graphics 5100
VRAM (Dynamic, Max): 1536 MB

ckoff, could you attach a screenshot of the broken rendering when you encounter it again?
Also, can you check how attachment 9100978 [details] renders on your machine? Does it match the "bad" rendering (attachment 9100978 [details]) or the "good" rendering (attachment 9100981 [details])?
