Using a 2013 macbook, I see a white background when I run `cargo run --example lorem-ipsum /Library/Fonts/Arial.ttf".

[pcwalton]

@jdm Can you retry now?

[jdm]

Still blank.

OK, I think I'll need to add some support for dumping the GPU in use.

If you get a chance, could you try downloading gfxCardStatus (http://gfx.io) and setting to "Integrated Only" and "Discrete Only" and trying to see if one of them works?

[jdm]

It works fine now, whether I'm selecting a particular card or using dynamic switching. That's very peculiar.

[pcwalton]

Yuck. Sounds like a driver bug.

Perhaps I can detect whether nothing is being output and disable Pathfinder in that case.

I encountered the same output on 10.12.3 on an iMac with an NVIDIA GeForce GTX 780M 4096 MB.

seeing the same with 2014 rMBP, NVIDIA GeForce GT 750M 2048 MB & Intel Iris Pro 1536 MB

certainly on the discrete part (external monitor attached)

I've tagged this issue as "classic", as it likely only applies to Pathfinder 1 ("classic Pathfinder"). Once Pathfinder 2 matures, this issue will be closed. Feel free to reopen if it is still an issue with the new version. Thanks!

[pcwalton]

This issue affected Pathfinder 1, which is now obsolete. Please feel free to reopen if this is still an issue with Pathfinder 2.
