I am unable to reproduce this issue on Firefox Nightly 79 with macOS. Clara, can you confirm this is still an issue?

Hi Micah, yes I'm still able to reproduce in nightly 79.0a1 (2020-06-10) (64-bit).

Let me know how else I can help. I can reproduce with multiple combinations please see attachment.

Best,

Clara

Ugh, I can't reproduce. I'm also on macOS. Clara, what value do you have for the gfx.webrender.all pref? To be clear, I can't reproduce with either value set, but it might be useful to see if you can only reproduce with a specific value.

Hi, I can reproduce both with gfx.webrender.all true and false.

Let me know if I can help with anything else!

Best,
Clara
