Example from Portal Stories: Mel. Upper picture: Shader quality "Very =
high" (or
high), Lower picture: Shader quality "medium" (or lower)
Hello,
this is my first bug report, so I hope the information provided is sufficie=
nt.
In Portal Stories: Mel and Portal 2 (reportedly), the player's arms and han=
ds
(and a few other objects, as demonstrated in the attached picture) appear b=
lack
when the shader quality setting is set to "High" or "Very Hi=
gh", but appears
normal if it is medium or lower.
This seems to only happen to a few objects, like the arms. In Portal 2 this=
is
not visible as often, as the player's arms are usually not visible like tha=
t.
Not sure if this is a Mesa bug, but it has been pointed out that the reports
have so far only been on different versions of Mesa, so.. just thought I'd
report it here in case.
I actually wanted to provide apitrace files, but I could not get it to work,
sadly.
I sorted this under radeonsi because this is the driver I use, but among the
other reports have been Intel systems. Please correct the bug report
classification if not accurate.
