Hi Team
Not sure whats going on.
Had Einstein working fine on my AMD RX480 with Ubuntu 17.10.
Yesterday I upgraded to the latest Ubuntu 18.04 and now when I have Einstein running the mouse/screen display will temporarily freeze for half a second and it repeats this every 3 to 5 seconds. Naturally this makes using the computer impossible lol.
When I disabled Einstein at Home the pc works as usual.
Quick Note: Einstein at Home is a distributed computer platform using my CPU and GPU, via OpenCL to perform work.
The issue is occurring under both Wayland and X11.
I am running the latest OpenCL stack/drivers on the GPU.
I am not only running the latest open source AMD/Mesa stack drivers from Ubuntu 18.04 but have gone one step over and installed the bleeding edge oibaf drivers to try and sort the issue.

(https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers)
I also manually installed the latest OpenCL driver:
"sudo apt install mesa-opencl-icd"
The problem still persists.
Boinc's log shows that it sees my GPU and lists its OpenCL attributes as well.
The pause of the mouse is also temporarily pausing the PC as well. Its more like a graphical 'glitch' that freezes the screen. The underlying subsystems hums along under the glitch with no issues.
I have an 8 core, 16 thread Ryzen CPU, even with it running 4 other boinc tasks it is no where near full capacity (about 35% utilisation in fact).
Suspending Einstein at Home returns the PC to normal operation.
The PC ran this setup fluidly under Ubuntu 17.10
