I am seeing a consistent behavior with the -dev and -nightly builds on both of my computers running Debian/sid. With dev/nightly the browser eats CPU cycles even with no extension loaded, no page shown, and minimized. CPU loads vary between 30% and 100%, and always two thread eating time.
With the beta channel nothing of this kind happens, without any interaction CPU load of brave threads drops to <3% percent.
Is this a known issue, or is there any advice how to debug this?
