--- Comment #1 from Francisco Jerez <currojerez at riseup.net> ---
This seems to be caused by the atan() built-in implementation now using
ir_triop_csel instead of control flow, which is translated incorrectly by the
mesa state tracker on drivers with native integer support when one of the
arguments is floating point and has a source modifier enabled, because
glsl_to_tgsi emits an integer UCMP instruction in that case, which has
different (integer) modifier semantics.
