Why is the patch function modifying the line width of existing lines?

Hello all, I am having some trouble with the patch function, whenever I use it it is changing the line width (at least apparently) of already existing lines. Here is a code example:
t=0:0.01:4
figure
plot(t,t.^2)
hold on
plot([1,1],[0,16],'--r','LineWidth',2)
plot([2,2],[0,16],'--r','LineWidth',2)
plot([3,3],[0,16],'--r','LineWidth',2)
patch([1,1,2,2],[0,16,16,0],'b','FaceAlpha',0.1,'LineStyle','none')
Before the patch command, the lines have a specific width, but after it they change! Has someone faced this problem before? Is there any solucion to it?
Thank you very much in advance,
Ana

When you add the patch() the renderer changes to OpenGL, as only OpenGL can handle transparency (FaceAlpha).
