<pre>Greetings,
After updating from Mesa 18.3.1 to 18.3.5, swaywm no longer starts on my
nouveau Nvidia GTX 770.
Sway prints the following error:
sway: ../mesa-18.3.5/src/mesa/program/prog_parameter.c:247:
_mesa_add_parameter: Assertion `0 < size && size <=4' failed.
I bisected it down to this commit:
<a href="https://gitlab.freedesktop.org/mesa/mesa/commit/fb78a6cb72270de271f75d6f6c9b5ebadba7a898">https://gitlab.freedesktop.org/mesa/mesa/commit/fb78a6cb72270de271f75d6f6c9b5ebadba7a898</a>
However, reverting that on top of my distro-provided Mesa 18.3.5 still yields
the same error.
Mesa 19.0.3 fails with a different message:
sway: ../mesa-19.0.3/src/compiler/glsl/serialize.cpp:555: void
read_uniforms(blob_reader*, gl_shader_program*): Assertion `vec_size +
prog->data->UniformStorage[i].storage <= data +
prog->data->NumUniformDataSlots' failed.
Please let me know what other details I can provide. Thanks in advance!
This is possibly a duplicate of #109812.</pre>
