CEF Build: cef_binary_95.7.18+g0d6005e+chromium-95.0.4638.69_macosx64
I was looking for help on my CEF browser application seemingly growing when I actuate mouse movements in an automated test environment.
My application is filtering on some NSEvent's in my NSApp sub class MyApp using an overload on sendEvent
Once I am finished, it super's to sendEvent. This creates memory that appears to leak in Instruments from the stack below. I build with ARC turned on, but when I wrap the code with @autoreleasepool {}, the below frame disappears from my live_allocations in malloc_history and the image shrinks accordingly. That brings up more questions than it really answered. Does CEF code build with ARC on by default? If the memory component is created with ARC/on, then I'd think that a release pool would be benign to the allocation. If it's created without ARC (GC), then (I read) a release pool will inspire the GC to operate faster, but I'm not sure why the GC wouldn't kick in during the hour of wall time that my test runs.
Thanks in advance.
