[virglrenderer-devel] [PATCH 0/4] Fix red-alpha blit

[marcandre.lureau at redhat.com]

From: Marc-André Lureau <marcandre.lureau at redhat.com>

stellarium and other Qt apps using QGLTextureGlyph have text rendering
issues with virgl. I traced down the problem thanks to vtest &
apitrace, however, I needed to workaround apitrace & epoxy with a new
glx backend that is proposed in this series (disable by default,
mainly useful for debugging).

Since arbitrary swizzling on texture formats doesn't seem necessary, I
simplified the VREND_BIND_NEED_SWIZZLE code to red-alpha trick only,
that allows to write a simpler solution for the tricky blit case.

Marc-André Lureau (4):
  Add a GLX backend
  vtest: add VTEST_USE_GLX environment variable
  formats: simplify red-alpha swizzle formats
  blit: fix blitting to red-alpha texture
