This was only seen if the display layer (virtio-gpu) did not directly share the dmabuf fd with Spice (i.e, blob=false). One of the main differences in the case where blob=true vs blob=false is that we create the dmabuf fd from a texture in the latter case whereas we directly pass the fd from the display layer to Spice in the former case. Although, the surface's format (PIXMAN_BE_b8g8r8x8) is the same in both cases, the creation of the texture (which involves copying data from Pixman image into a GPU buffer) appears to somehow result in having the R and B channels interchanged. One way to ensure correct behavior is we have glformat=GL_RGBA while creating the texture. It looks like having glformat=GL_RGBA and gltype = GL_UNSIGNED_BYTE should work regardless of the Host's endianness but let us limit this change only to this specific use-case for now.

Therefore, ensuring that the memory backing the texture has a linear layout is absolutely necessary in these situations. Note that, requesting GL implementation to create a texture with linear memory layout can only be done using memory objects. And, a memory object can be created by importing a dmabuf fd.

Note that, there does not seem to be a direct way to indicate to the GL implementation that a texture's backing memory needs to be linear. Instead, we have to do it in a roundabout way where we first need to create a tiled texture and obtain a dmabuf fd associated with it via EGL. Next, we have to create a memory object by importing the dmabuf fd created earlier and finally create a linear texture by using the memory object as the texture storage mechanism.
