This might be either mac or AMD specific. I wasn't able to reproduce this on my machine, but this user saw it on a Macbook Pro with an AMD GPU. It occurs when zooming in and viewing the polygon from certain angles. See the forum post for more details.

This is may be a bug in the AMD driver. This works on my MacBook Pro with NVIDIA. Are they running the latest version of OS X?

hpinkos commented 9 years ago

He said he's running OSX 10.10.5 (Yosemite)

hpinkos commented 9 years ago

Also reported by this user: https://groups.google.com/forum/?hl=en#!topic/cesium-dev/iBuJiV2-EkE Running OSX 10.11 and an AMD graphics card.

slightHYP commented 8 years ago

I confirm the bug:

Mac Pro OSX Yosemite 10.10.5 2 x 3 GHz Quad-Core Intel Xeon 12 GB RAM ATI Radeon HD 5770 schermata 2016-02-01 alle 13 05 24

I will try to update the OS.

chriseyhorn commented 8 years ago

I am also getting this error on my Mac running 10.11 with AMD graphics card. Same behavior across Chrome and Safari. Everything looks fine until I get to a specific zoom level and then it looks like the other screen shots above.

slightHYP commented 8 years ago

Hi everyone, any news about this issue...Probably is not related directly with CesiumJS core, more with the ATI drivers... but, anyhow, do you have any suggestion, workaround or fix?

Mac Pro OSX El Capitan 10.11.5 2 x 3 GHz Quad-Core Intel Xeon 12 GB RAM ATI Radeon HD 5770

Thank you, Michele

pjcozzi commented 8 years ago

@slightGT no update yet, but I suspect we will need to add a workaround in Cesium since Apple does not update drivers often.

We are currently improving polygons on terrain for 3D Tiles (#3241) so there's a chance we will also fix this in the process.

slightHYP commented 8 years ago

@pjcozzi Thanks, I will follow the improvements in the 3DTiles branch.

douglasbodkin commented 7 years ago

I am also experiencing this issue on a 2015 MacBook Pro (AMD Radeon R9 M370X 2GB; OS X El Capitan 10.11.5) and a 2016 MacBook Pro (AMD Radeon Pro 455 2GB; macOS Sierra 10.12.4). The first screenshot shows the polygon while zoomed out and the second displays the issue while zoomed in:

pjcozzi commented 7 years ago

@douglasbodkin when you visit http://webglreport.com/, does it report "EXT_frag_depth" at the bottom?

douglasbodkin commented 7 years ago

@pjcozzi Yes, it lists "EXT_frag_depth" at the bottom. Here is the full report:

pjcozzi commented 7 years ago

Thanks @douglasbodkin, I was afraid that would be the answer! 😄

mramato commented 7 years ago

I can reproduce this locally as well (on the old Mac we have, which is also an AMD card).

pcmehlitz commented 1 year ago

it seems this is still pertinent on current Apple hardware (M1/M2) - see https://community.cesium.com/t/macos-driver-bug-for-small-clamp-to-ground-polygons/24277
