I think i found the problem.

substitute app with "VMware fusion" or what ever app is causing this.. I'll include VLC here as well..

I found plenty of .GPUresets in %home%/library/Log folder..

I am gonna do a clean install of Mojave, this time without the security update, and test... i believe its solved.
