dolphin-emu-e1a76b4_2016.07.12-x86_64-1_git

When using "Pause on Focus Lost" under config/interface and then switching to another window a single cpu core (AMD FX-6350) throttles at 100% until I switch back to dolphin-emu as the active window. Disabling the feature stops the problem and using gdb I found thread 5 as the possible culprit and got this backtrace.
