After starting the OpenCL program, there will be a blurry screen, and then drive Crash
Maybe the driver has set an upper limit on the OpenCL process, more than 8 processes will inevitably crash
console prompt:
Memory access fault by GPU node-1 (Agent handle: 0x404b0d0) on address 0x7f828d0ac000. Reason: Page not present or supervisor privilege.
The same program and data, 5700XT is normal in Ubuntu18.04 and an old version driver, and it can also work normally with Nvidia graphics card
