"dark mode" is nice in theory, but the effect is completely broken as soon as anything non-dark slips through.

for instance (on windows at least) the program "OBS" uses a dark theme; in a recent version, when you open up any settings window, the window is drawn for a few milliseconds as a bright white square, before the dark window 'renders' [0]. this sudden strobe of white light, without warning, is worse than if the interface was just bright all the time (imo)

this flashing light issue has also plagued chromium off and on for over 10 years. [1]
