Yes please file a issue here and also link the SteamVR bug report. Oh having the hello_xr app reproduce it will make it a lot easier to fix for us. My current hang-up is that the colour space of a GL_RGBA buffer should be linear not sRGB, but again I'm not a colour space expert.

Hello, sorry if this is the wrong place to ask this.

Hello, I'm one of the developers on Monado. Color space conversion isn't one of my strong sides, and I will admit that we could be doing things wrong inside of Monado. Right now we expose two swapchain formats GL_SRGB8_ALPHA8, and GL_RGBA8[1]. Which are converted to VK_FORMAT_R8G8B8A8_SRGB and VK_FORMAT_R8G8B8A8_UNORM in the Vulkan side of the compositor[2]. We are also by default using a sRGB non-linear color space for the swapchain[3], so it should be all working as long as you use the right format.
