OpenGL error GL_INVALID_ENUM detected at engine/renderer/tr_backend.cpp:2879 with Q3Rally map

[illwieckz]

Q3Rally is a Quake3 mod that became standalone, there is no reason Q3Rally maps would not load and render properly, otherwise that means we have a bug or a regression in the engine.

When loading the nightcity map, I get this warning spammed in some place:

Warn: OpenGL error GL_INVALID_ENUM detected at …/src/engine/renderer/tr_backend.cpp:2879 

How to reproduce:

• Download Q3Rally_v0.3c_linux64.zip from this place
• Extract the baseq3 folder from that archive and move it right to daemon
• Run the game with a command like that: ./daemon -homepath /tmp/unvq3r -pakpath baseq3r/ -set fs_legacypaks 1 -set fs_extrapaks 'q3rpak0 textures' -set r_checkGLErrors 1 -set g_neverEnd 1 +devmap q3r_nightcity
• Teleport to a place triggering the bug: /setviewpos -110 -1550 200 -90 0
