Git commit 7236d4457d5b345dacadc22936e00d1bfac507ae by Boudewijn Rempt.
Committed on 25/05/2016 at 12:10.
Pushed by rempt into branch 'master'.

Add note about gllogicop

Though I think that on AMD, it doesn't work even if it's defined,
so We still need to figure out another way to draw the cursor.

I suspect this code in kis_opengl_canvas2.cpp:

// XXX: glLogicOp not in ES 2.0 -- it would be better to use another
method.
// It is defined in 3.1 core profile onward.
glEnable(GL_COLOR_LOGIC_OP);
if (ptr_glLogicOp) {
ptr_glLogicOp(GL_XOR);
}

I just sent a couple of screenshots of what the cursor looks like in Krita 3.0
Beta.

Also please note the garbled text on the upper left corner of the canvas in the
screenshot with OpenGL enabled. Don't know what's that supposed to be it's
unreadable and it changes all the time (some kind of coordinates?)

No the brush cursor wasn't like that in 2.9.11

What the cursor is supossed to look like.

The thing is that the green cursor is supossed to be mixed in with an exclusion
blending mode, like in the screenshot I attached.

So there must be an openGL problem here. Did this also happen in 2.9.11?
