I also have the same problem as the author of the iced issue. I was originally investigating why iced doesn't display text in its examples.

AdapterInfo { name: "Radeon (TM) Pro WX 4100", vendor: 4098, device: 26595, device_type: DiscreteGpu }

operating system is Windows 10 Pro for Workstation Version 10.0.17763 Build 17763. tried with stable (rustc 1.39.0 (4560ea788 2019-11-04)) and nightly (rustc 1.40.0-nightly (38048763e 2019-11-06)) windows msvc toolchains.

Could you confirm your graphics drivers are up-to-date?

It's hard for me to debug this, as I can't really reproduce the issue. I am guessing it is probably related to texture sampling, as the other affected user has reported in https://github.com/hecrj/iced/issues/96 that they cannot see images either.

Maybe running with RUST_LOG=debug can give us a hint about the issue.

Another thing worth trying might be running the cube example in wgpu and see if it shows the Mandelbrot texture.

the cube example worked ok. I updated my drivers (from 23.20.15018.16 to 26.20.11018.4005) and now I can see text! Iced works too. Thanks!

hey I'm running a mac pro, mojave. Intel Iris Graphics 6100 1536. I have the same issue, mandelbrot wgpu-rs demo works fine, but the example for wgpu_glyth just displays a grey background.

luke-titley commented 4 years ago

Actually. Don't worry about this. I made some changes to wgpu_glyph to get it to build against wgpu-rs master branch and I think I introduced an error, so don't worry about this.
