Summary0032533: Visualization, TKOpenGl - suppress error reported on Intel drivers due to OpenGL 4.5 specs violation
DescriptionThe following error is currently reported on Intel drivers:
TKOpenGL | Type: Error | ID: 0 | Serverity: High | Message:
OpenGL context reports version 4.6 but does not export required functions for 4.5 (glGetnCompressedTexImage)
Please report this issue to OpenGL driver vendor 'intel' 


It seems that Intel engineers are not going to fix the bug in a meaningful future (it is already 2 years passed since first reports).
Therefore, it is proposed lowering message priority for this specific issue.
Steps To ReproduceN/A
TagsNo tags attached.
Test case numberNot required

0032533: Visualization, TKOpenGl - suppress error reported on Intel drivers due to OpenGL 4.5 specs violation

OpenGl_GlCore45 - removed a couple of FFP-related functions introduced by OpenGL 4.5 Compatible Profile, but not Core Profile.

OpenGl_GlFunctions::load() now tries to load a set of functions
from GL_ARB_robustness extension (having ARB suffix) to fill OpenGL 4.5 function table,
and from GL_ARB_indirect_parameters extension to fill missing items in OpenGL 4.6 function table on Intel drivers.
Warning message (trace level) is now reported instead of error in case of fallback usage.
