From a65d6a11cb82719a649110a8deaeb8f87e1c374b Mon Sep 17 00:00:00 2001 From: Greg V Date: Sun, 31 May 2020 16:53:57 +0300 Subject: Add custom window background/clear color (incl. transparency) support, fixes #272 wgpu would currently ignore the alpha: https://github.com/gfx-rs/wgpu/issues/687 glow (and naively patched wgpu) requires premultiplied alpha, so if you don't multiply the RGB by the A right now, the semi-transparent color would be wrong (too bright). winit with_transparent doesn't seem necessary. --- wgpu/src/settings.rs | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'wgpu/src/settings.rs') diff --git a/wgpu/src/settings.rs b/wgpu/src/settings.rs index 4655e64f..16294ba3 100644 --- a/wgpu/src/settings.rs +++ b/wgpu/src/settings.rs @@ -1,10 +1,11 @@ //!
