He meant "Switch macOS from dark mode to light mode", that will help you with the dialog readability, patches for which are already commited in the source tree for the next release.
It will of course not help you with the black artifacts around lights on the charts
, those I have never seen as far as I can tell (but my Mac hardware
is somewhat newer than yours). You may try to go to Toolbox -> Display -> Advanced -> OpenGL Options button and turn off the various smoothing options, but I don't have very high hope it will help.
Edit: Of course also try to disable all the plugins you have installed to discard the possibility some of them does bad things to the OpenGL stack.
