[Bug 1459613] Re: connecting 2x 4k screens on a Dell XPS12 (9Q33): compiz crashed with SIGSEGV in GLTexture::matrix() from GLScreen::glPaintCompositedOutput
So i tried a new clean install with 15.10 and now it works very nicely!
I'm suspecting the upgrades from 14.10/15.04 or the troubleshooting
steps have broken something.
I also got a reason why the 2x4k and 1x2k resolution does not work;
"exceeds 3D hardware limit (8191, 8192)"
I made a screenshot of the full error.
I'm still curious if this could be fixed in Ubuntu as it does seem to
work in Windows. It might not be a serious issue and not at all required
for me, but if this proves to be an underlying issue in Ubuntu with
higher resolutions this might be a problem in the future with all the
high-res screens that are coming.
