Its looking like the use of the eglCreateImageSyncKHR extension is causing thread activity (creation/destruction/TLS).
Once mir started using these functions, it caused this timing increase in Mali cores, and lp: #1524414 in powervr ones. Linked to hybris, as its looking like this is a hybris/glibc threading issue. For mir, we can disable the use of these sync extensions on mali, until we can fix the deeper TLS problems.
