Linux-driver on Ubuntu 14.04.4/64-bit with card AMD/ATI Richla=
nd Radeon HD
8570D
(AMD Radeon R7 240):
it seems that "glLogicOp (GL_XOR)" does not work:
..
glLogicOp (GL_XOR);
glEnable (GL_COLOR_LOGIC_OP);
..
glPixelZoom (1.f, 1.f);
glDrawPixels (rb_dx, rb_dy, // width, height
// GL_BLUE, // yellow
GL_GREEN, // violet
// GL_RED, // cyan
GL_FLOAT,
fBuf); // data
glDisable(GL_COLOR_LOGIC_OP);
creates a black background only.
Sourcecode: see function GL_RubberBox_draw in:

code.

Ubuntu 14.04 is a bit dated. Is it also broken on latest Mesa = git?

my problem is solved; after: sudo apt-get build-dep mesa - this did install (add !) several packages *drm* *llvm* .. - now the selection-box (rubber-box - by glLogicOp (GL_XOR)) works !
