Bug 105568

Mesa 17.2 -> 18.0 is pretty big jump, any chance you could try if 17.3 release works or bisect the failure? Problem clearly is that some shader program fails to link.

Hi,

I have the same problem with World Of Warcraft, also on Ubuntu Bionic Beaver 18.04 LTS amd64 (beta), but with an Radeon RX-560:

0039:err:d3d:wined3d_debug_callback 0x177338: "GL_INVALID_OPERATION in glGetUniformLocation(program not linked)".

[...] 273250 more lines like theses follows in syslog.

On this game I simply don't see some models (seems to be the MD2 based one) like characters/game objects...

Note: On my stable OS (Ubuntu 16.04 LTS amd64), this bug do not exists.
Downgrading to Mesa 17.* on Ubuntu 18.04 ... is complicated!

Probably a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=105426

It is fixed for me with mesa 18.0.0-rc5

Thanks for testing, assuming duplicate for bug #105426

*** This bug has been marked as a duplicate of bug 105426 ***

Confirmed fixed in 18.0-rc5.
