kwin_x11 GLES support?

So I got a new ARM based chromebook lately, using Mali graphics.  I prefer to use KDE, with some compositing features (not just eye-candy, some of it is actually practical).  Right now, the compositing effects are extremely slow, because it seems everything is CPU rasterized with openGL, when I could be doing GPU acceleration with GLES.

Anyway, I'm aware KDE (before KF5 and plasma 2) had a "kwin_gles --replace" option.  But that binary is now gone, and to my knowledge, the new kwin_x11 binary must be compiled to support either regular openGL or GLES.  What I don't know, however, is if the ARM version of kwin is like this.  I figure it should be, since (to my knowledge) all GPU-accelerated ARM devices support GLES, but not all support regular GL.  Does anybody know a way to prove this, or, how I can set kwin to compile with GLES whenever updates occur?

I'd gladly use kwin_wayland but I get an error (I forget what it is, I'll have to check later)

Re: kwin_x11 GLES support?

On the top right of the page click "Packages". Then: Package Actions -> Source Files and view the PKGBUILD. You might have to look at the dependencies as well. Once you found it, read the wiki article of ABS for easy rebuilding. The rest is up to your scripting imagination (sed on a PKGBUILD and some pacman wrapper checking for your ABS stuff) or maybe you want to maintain an AUR package.
