Apple Silicon OpenGL slows down emulation speed

Describe the bug

In macOS on Apple Silicon the OpenGL modes have an odd side effect of slowing down emulation speed. A couple programs and games i've tested seem to go under 100% realtime unless i go unreasonably low cycle count if i use OpenGL for drawing. If i use Surface rendering i can use at least 19k more cycles without dropping off from 100% realtime speed. Changing the core type does nothing, this is purely the rendering "doing something" to the processing speed,
Steps to reproduce the behaviour

Be using Apple Silicon M1 Mac Mini 8GB RAM model running macOS 12.4
load up dosbox-x
configure dosbox-x to use any OpenGL mode (maybe being in a retina resolution matters, but i'm unsure, i do use a 4k TV as a monitor though)
normal core type. pentium pro, anything above like 486dx2 66mhz cycle count
run something like heretic or robocop 3
have movement on the screen
after a second or two it'll just drop from 100% to like 80-90%
do the same as above but change to surface rendering and normal 4x scaling and you wont have the same slowdown issue
