Windows boosts thread priorities (https://docs.microsoft.com/en-us/windows/win32/procthread/priority-boosts) based on undocumented algorithms (but the fact that a window receiving events gets a boost is clear).
This causes unexpected complications for us because the parent process gets a boost, making it have a higher priority than the GPU process and content process, that the parent is waiting for.
Seeing the actual current dynamic thread priority in the profiler may help us find solutions to cases where the process we are waiting on doesn't get scheduled on machines with few cores.
Severity: -- → N/A
