From: Erik Faye-Lund Date: Tue, 9 Jun 2020 19:25:26 +0000 (+0200) Subject: gallium/hud: do not specify potentially invalid depth-range X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=67ad75a282d11f4c284e30ddc8848550f02a6948;p=mesa.git gallium/hud: do not specify potentially invalid depth-range Setting the depth-scale to 1 while leaving the depth-translation at 0 means our near-plane is at -1 in OpenGL semantics, which is out-of-range on some drivers. In particular, Zink has this limitation. But since we'll only pass a zero z in here anyway, we might as well multiply it by zero, and get the same result. This avoids the problem.
