I have big problems with the latest 4.18.16-96 update of the linux-current package. Many graphical glitches, main display will stay black after X.org has started up most of the time and the system is left mostly unusable. If I boot up Windows or the kernel update before that, version: 4.18.14-95, it works perfectly again.
System info:
CPU: Intel i5-3570k
GPU: AMD R9 280X, running with amdgpu
