Direct2D QPA
Unsolved
General and Desktop
-
Since around Qt 5.3, a direct 2D QPA was introduced. Using this platform enables the Direct2D paint engine, which makes all QWidgets on the screen be rendered using hardware acceleration. This seems a big deal, since the last experiment with OpenGL was dropped, but I haven't seen any official announcement regarding that.
What is the Direct2D QPA status? Should we use it or not? What is its performance? Known issues?
