+Subject: [PATCH 1/2] [glplugin]gleffects: fix little rectangel appears at the
+ center when use squeeze and tunnel effects
+
+These two shader will calculate the verctor length and use it as denominator.
+But length could be zero which will cause undefine behaviour. Add protection for
+this condition
+
+Upstream-Status: Backport [1.8.3]
