DOOM is hitting some isl_surface_state.c asserts since when they have been
added:

mon\DOOM\DOOMx64vk.exe: isl/isl_surface_state.c:488:
isl_gen9_surf_fill_state_s: Assertion `info->view->swizzle.b ==
ISL_CHANNEL_SELECT_RED || info->view->swizzle.b == ISL_CHANNEL_SELECT_GREEN ||
info->view->swizzle.b == ISL_CHANNEL_SELECT_BLUE' failed.
mon\DOOM\DOOMx64vk.exe: isl/isl_surface_state.c:485:
isl_gen9_surf_fill_state_s: Assertion `info->view->swizzle.g ==
ISL_CHANNEL_SELECT_RED || info->view->swizzle.g == ISL_CHANNEL_SELECT_GREEN ||
info->view->swizzle.g == ISL_CHANNEL_SELECT_BLUE' failed.

Printing out the values shows that .g and/or .b are sometimes 0.
>From some limited testing, no rendering problems noticed in release build (or
with those asserts commented out).
