[Glamor] Gradients are broken with glamor when RepeatReflect is set

[Pasqual Castellón]

HI Chris,
Could this problem be related with this other?

Dear Sirs,

I have a problem with xlib output refering to XSetDashes. The dotted
lines using 2 array length is working (eg 1,1) but when I use a longer
array length it does not work (eg 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1). Then
the line is showed as dash-dot and not as dot.

It used to work with CentOS but now the problem appeared after
installilng fedora 26. Any clue?

I think this problem is possibly related to glamor module using NOUVEAU.

This is a sample code:


Pasqual.
