I see the problem with poppler_qt4viewer as well.

Created attachment 131940 [details] test case In the attached test case, we stroke a rectangle using a shading pattern. The stroking alpha constant (CA) is set to 0.25 but the stroke is drawn opaquely. It seems to use the nonstroking alpha constant (ca) instead, which is still at the initial value of 1.0. The test case draws two more shapes for comparison. 1. stroke a rectangle with a solid colour: the stroking alpha constant is respected in this case. 2. fill a rectangle with the shading pattern; the nonstroking alpha constant is respected.
