KWin 5 To Drop Its OpenGL 1.x Compositor

KDE

KDE's KWin compositor will be dropping its legacy OpenGL 1 compositor with the upcoming KWin 5 Alpha release.

Due to KWin 5 relying upon Qt Quick 2 and that in turn relying upon GL2/GLES2 scene graph, Martin Gräßlin is finally going for dropping the old OpenGL 1 compositor back-end. Martin has talked about taking such a move in the past but now he's finally going ahead and dropping this pre-GL2 code.

KWin's main compositor is written for OpenGL 2.0 while for older, vintage systems not doing too well with its 3D support there is also the KWin X RENDER back-end. Martin mentioned details of dropping the old GL1 support in a blog post today entitled House Cleaning in KWin 5, besides his post earlier about the state of Wayland in "KDE5" code.
