I did some 'gdbing' and located cause of the issue.

The problem (only?) happens when texture compression is enabled.

So, if texture compression is enabled GLFramebufferObject::allocate
allocates texture that is compressed and apparently mesa doesn't like
compressed textures for frame buffer.

Oddly enough enabled compression doesn't cause the problem when texture
is allocated first time at startup, but only causes problem when it is
reallocated when resolution changes. Probably because custom config is
loaded at a later stage somehow - but this is not exactly apparent why
config is loaded at a later stage. Judging by the log output config
should be loaded by the time opengl plugin is loaded.

I guess ideally enabling texture compression should not cause such
issues.

Please let me know if I can provide any other information.

Thanks!
