weird colours and blurriness

[bananaturtlesandwich]

hi just a couple questions since I recently ported my application to wgpu

• the application is very blurry is there anything I can do to fix it? before I was using eframe with wgpu backend and it wasn't like this

I'm now using winit and I've compiled this manifest with winres as well so not sure why this is

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">
  <asmv3:application>
    <asmv3:windowsSettings>
      <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>
      <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2</dpiAwareness>
      <gdiScaling xmlns="http://schemas.microsoft.com/SMI/2017/WindowsSettings">true</gdiScaling>
    </asmv3:windowsSettings>
  </asmv3:application>
</assembly>

also the colours seem to be off - the meshes shown above use vec4(0.2, 0.5, 1.0, 1.0) for colour which should look like this

the code is on this branch if anyone would like to help

thank you!

got an answer!
eframe does some sort of anti-aliasing (probably MSAA). You can find how to do this in the msaa-line example in the wgpu repo. Although SSAA looks even better for drawing those kinds of dense wireframe objects which you can also accomplish in wgpu.

The reason the color looks different is probably due to the sRGBness of the surface texture. There are two ways you can fix this:

1. force the surface texture to always be sRGB / non-sRGB and adjust your color accordingly. Although this could be problematic because not all platforms support both sRGBness for the surface

2. query the surface's sRGBness for the surface format that was chosen by wgpu, then pass that flag to your shader with a uniform parameter and do the srgb-linear conversion yourself depending on that flag
