Shadow Flickering
Closed this issue · 0 comments
Description
Shadows will constantly flicker in the 3D test scene on Linux, Vulkan, AMD GPU.
Potential Fix
Someone linked me this, which worked.
https://github.com/bevyengine/bevy/blob/release-0.14.2/crates/bevy_render/src/renderer/mod.rs#L393-L400
Change force_serial
to true
.
Looks as if it's a problem on windows too, and someone has fixed it there, but not fixed it for linux.
Repro steps
https://bevyengine.org/examples/3d-rendering/3d-scene/
Happens here if you're using linux, vulkan, amd gpu.
Expected vs observed behavior
Expect a stable shadow, looks like the absence of light.
Get a constantly flickering shadow, like a rave but not as loud or annoying.
Stack
Linux (I'm using arch endeavour but don't think it matters), Vulkan backend with amd gpu/drivers.
