Subject: Fix undefined behavior in record_variable_selection test.
X-Git-Tag: upstream/0.1.0~2008
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a3c1058eb8af4c3440cf1223e5e60e5876174f0c;p=platform%2Fupstream%2FVK-GL-CTS.git

Fix undefined behavior in record_variable_selection test.

Tessellation shader expects patch size >= 3. Increase shader input
patch size to 3 from 1.
