When Use Kaby Lake-g(AMD Vega M GPU) to do the OpenGL CTS test, the case " KHR-GL43.compute_shader.max" will fail. KHR-GL44.compute_shader.max and KHR-GL45.compute_shader.max also failed Following is the environtment Platform KabyLake-G CPU Intel (R) Core (TM) i7-8809G CPU @3.10GHz GPU AMD(Radeon RX Vega M GH Graphics); Memory 16G OS Ubutu18.04 Kernel 4.19.0 Mesa: mesa 18.3.0 (https://mesa.freedesktop.org/archive/mesa-18.3.0.tar.gz) VK-GL-CTS version https://github.com/KhronosGroup/VK-GL-CTS commit 54e546a1a0a6fa412ea4c3e3081bbc9518928a6e How to reproduce run command: $ ./glcts -n KHR-GL43.compute_shader.max Writing test log into TestResults.qpa dEQP Core git-54e546a1a0a6fa412ea4c3e3081bbc9518928a6e (0x54e546a1) starting.. target implementation = 'Default' Test case 'KHR-GL43.compute_shader.max'..

Is there any update for this issue? Thanks
Is there any additional information needed for this bug? Thanks.
The test checks the value of GL_MAX_COMBINED_COMPUTE_UNIFORM_COMPONENTS using glGetInteger64v. The returned value is greater than 2G. The test incorrectly converts the value to GLint, which ends up being a negative number. This is a test bug.
