It generally is. Drivers have slowly stopped using many of the hardware
acceleration as 2D acceleration in many cards have languished and it is often
faster to do in software, or the hardware accelerated ones are very limited
types of operations, that are basically unused in modern application (almost
all non-antialiased for instance). There is a reason Xorg has been abandoned
by its own core developers in favor of Wayland.
As for the code you showed, that is so 90s. Please enable anti-aliasing, and
try again. Or do any kind of advanced pattern or line endings and joins.
