Yep. Part of the reason Scribus and other OSS apps may not be bothered
is that they tend to use an indirection layer for their graphics to make
things portable. Scribus barely uses accelerated drawing features, if
it does at all - it draws to off-screen bitmaps (often using pure CPU
resources not even window system memory and operations) then blits it to
the canvas. On a side note, this has a speed penalty, but most of the
speed problems people run into on the Scribus canvas are not related to
this approach, but rather to redundant redrawing and the text layout code.
By contrast, many win32 "professional" apps will have drawing layers
that're highly optimised to the win32 drawing APIs, and dependent on
advanced features working correctly. Old drivers may cause big problems.
