Description of problem: After updating Cauldron this evening, including the new kernel noted above, Mesa OpenGL is indirect only and performance with foobillardplus and glxspheres64 is greatly degraded. Re-booting with kernel-desktop-5.0.7-4.mga7 restores normal operation. The kernel module is amdgpu selected for use with AMD Kaveri provided by APU A10-7860K Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Apply kernel update to kernel-desktop-5.0.7-5.mga7 2. re-boot and run glxspheres64, noting the poor framerate and jerky rendering 3. re-boot to kernel-desktop-5.0.7-4.mga7 4. repeat glxspheres64 test and note improvement

This is trippy. A few re-boots later and everything is back to normal with the new kernel. Sorry for the noise, but it really did happen for the first couple of boots with the new kernel.....

We believe you, we've seen stranger things ;-) I'll let the kernel maintainers decide what to do with this report.
