@mabysh thank you for filing! The crashes are not in wgpu-rs, they are in Vulkan validation layers. Please update your validation layers, or run in release (to avoid enabling them), and see how it goes.

mabysh commented 3 years ago

@kvark I already have installed latest vulkan-validationlayers package from Ubuntu repositories. Are there any other ways for updating vulkan layers? Running examples in release mode helped for Vulkan backend indeed. But OpegGL is broken: Screenshot from 2021-04-16 10-31-12 Screenshot from 2021-04-16 10-31-23

I don't remember if OpenGL backend worked for me in 0.6 releases, but Vulkan definitely worked in both debug and release modes on the same machine. Can anything be done to make it work in debug? Release not always suitable for developing.. Thanks!

cwfitzgerald commented 3 years ago

@mabysh take a look at https://vulkan.lunarg.com/sdk/home#linux to get the latest SDK with the most recent validation layers. They have their own ubuntu packages.

mabysh commented 3 years ago

@cwfitzgerald @kvark It's working now! Many thanks you guys for help, closing the issue.

kvark commented 3 years ago

OpenGL backend needs work, it's known to be very rough atm.
