Intel Iris - Colours wrong when using Vulkan - Only in Fullscreen

When running Dota 2 with the Vulkan renderer all the colours are off. However, when I screenshot using the steam overlay, the colours are correct. Below is a photo of the actual colours in-game and then a screenshot using steam overlay.

When running in windowed mode the colours are also correct.

I have tried running the -nogammaramp launch parameter but that did not appear to do anything. Only other parameter is -console.

I have tried using three different versions of VulkanRT, with the latest version currently installed (1.1.73.0)

There are some render errors in the console on startup Gist of console: https://gist.github.com/kreshim2018/19c34fc076fbea098abf42bc15a41151

I have seen a massive performance increase using Vulkan, however everything is also blue..

Intel has looked into this and it is a driver bug impacting Windows RS3+ on Kabylake+ hardware. There is a potential workaround I can look into which would be choosing VK_FORMAT_B8G8R8A8_SRGB for the swapchain instead of VK_FORMAT_R8G8B8A8_SRGB. But it should also be fixed in a future driver update.

So when is this being fixed? or what steps can we use to fix it ourselves?

Hello Indiana,

This was fixed for me a few weeks after I posted. Intel released updated drivers for Iris that rectified the issue.
