QT widget based UI rendering slow on qt5 when ported from qt4

[linuxsnail]

@SGaist Sure that's what I am doing right now but on a separate note is it possible to use any software acceleration with QTWidgets?

[SGaist]

What software acceleration do you have in mind ?

[linuxsnail]

@SGaist i just want to understand can opengl or svg libraries be used without gpu or any other backend like directfb can improve performance rendering apart from linuxfb

[SGaist]

You can use mesa for software based OpenGL rendering (don't expect hight performance).

SVG is not a screen rendering backend.

IIRC DirectFB should be faster than plain LinuxFB.

@SGaist Ok I believe qt 4 has qt-gfx driver which provides some sort of software acceleration when used with linux fb, any idea qt5 has any such driver which I can use?

[SGaist]

You have the complete list of backend available here.
