Proprietary Nvidia is affected, Mesa/Nouveau is fine.

Hey @Darkspirit, Thanks! Nouveau are working just fine. But, what's the problem with proprietary ones?

My first naive guess was that it's related to depth, but I can't assess that.
Debug and Release builds made on proprietary Nvidia are affected.
A fresh build from https://dl.servo.org works on proprietary Nvidia.

Builds made on proprietary Nvidia are not black on Mesa/Nouveau, only on proprietary Nvidia.

Yes @Darkspirit, I confirm that builds available at dl.servo.org are working on both proprietary and Mesa/Nouveau drivers. But, we still don't know for sure, why are they failing to work as intended on build from sources? Is there a regression somewhere? Relating to that, perhaps, how the versions are named might help us in finding that. Particularly, version Servo 0.0.1-70d4e142f is working find as of now.

This bug happens on Arch Linux too, GTX 1070. Let me know if more information would be helpful.

EDIT: servo.org builds are broken too, it seems. I tried the latest nightly as of the time of writing (June 11th 2020 5:56 PM EST).

I'm also encountering this issue with Nvidia proprietary drivers. I didn't compile Servo, rather, I downloaded the latest nightly build from the website.

Same problem with both a local build and the download from servo.org. Switching to nouveau drivers fixes the issue, but would be nice if it worked with the blob driver also.

It's interesting; this sounds very similar to the problem described in servo/surfman#173 that was fixed by servo/surfman#178, but we should already be using a revision of surfman that includes that change.

Possibly servo/surfman#178 (comment) is the strategy we should be investigating instead.

FWIW, servo prints libEGL warning: DRI2: failed to authenticate, no idea if that's related, but from the issue you linked, it sounds like this symptom can be caused by OpenGL API problems, so I thought I'd mention.

Same is happening to me, on Pop!_OS 20.04 with Nvidia proprietary drivers :/
