Description FERLET Patrice 2014-08-23 14:38:52 UTC
Created attachment 105161 [details] glxinfo outuput Trying some examples with THREE.js library in Firefox and Chrome/Chromium, Linux based system with intel graphic cards shows inverted bumpmap. You can see the example here: https://github.com/mrdoob/three.js/issues/4157 It seeme that the problem appears long time ago (2013 for this issue). I'm not sure about my driver version. I send you glxinfo output from my Fedora 20 installed on lenovo b590 laptop.

We've come a long way since Mesa 10.1.5. Can you try with one of the 10.2 stable releases? 10.2.6 is the most recent.
Comment 3 FERLET Patrice 2014-08-28 12:16:51 UTC
Same with 10.2 version. Installed from kwizart testing repository. The bump-map on chrome and firefox webgl examples (as my own projects) are inverted. OpenGL version string: 3.0 Mesa 10.2.5

Just now checked with mesa master branch and it is still reproducible. I will take a look to this.

Created attachment 108887 [details] Sample simple application using three.js To use this app you will need a local http server due to security restrictions for JS to access local files. In a GNU/Linux box, something like this should work: $ tar xzpf fd82991-test.tar.gz $ cd fd82991-test $ python3 -m http.server & $ xdg-open http://localhost:8000/fd82991-test.html &
