Bug ID: 95406 Summary: glLogicOp (GL_XOR) does not work on AMD/ATI card Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: franz.reiter@cadcam.co.at
Linux-driver on Ubuntu 14.04.4/64-bit with card AMD/ATI Richland 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: https://github.com/gcad3d/gcad3d/blob/master/src/gr/ut_GL.c
The proprietary AMD/ATI-driver and all Nvidia-cards/drivers work ok with this code.

--- Comment #1 from Vedran Miletić rivanvx@gmail.com --- Ubuntu 14.04 is a bit dated. Is it also broken on latest Mesa git?

--- Comment #2 from Franz Reiter franz.reiter@cadcam.co.at --- 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 ! Thanks.
