Bug ID: 92247
Summary: weston: black surfaces with mesa 11.0.2
Product: Wayland
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: weston
Assignee: [email protected]
Reporter: [email protected]
Weston 1.9.0 build with mesa 11.0.2 shows all surfaces as black squares.
Reverting to mesa 11.0.1 works OK.
A bisect revealed that the problem started showing up with this commit in mesa:
http://cgit.freedesktop.org/mesa/mesa/commit/?id=f15a7f3
Weston uses GL_BGRA_EXT/GL_UNSIGNED_BYTE as format/type for textures and this
is now rejected as invalid by mesa with this commit.
But according to GLES spec 3.0.4, section 3.8 texturing, page 127 (ie page 140
in this pdf https://www.khronos.org/registry/gles/specs/3.0/es_spec_3.0.4.pdf)
there is no indication of neither GL_BGRA or GL_BGRA_EXT being valid, so mesa
seems right to reject it.
Using a valid GL_RGBA/GL_UNSIGNED_BYTE is not rejected but obviously does not
show the right colors.
