Irritatingly, some windows applications implement their own subpixel rendering. As somebody on a 1440p BGR panel, those applications become extremely obvious to me as the aliasing is exactly backwards to what it should be. One irritating example is the web version of MS Word, as it doesn’t use the browser font rendering and instead implements it’s own (in canvas I think?) - giving all text eye-straining fringes on my display. Google Docs has the good sense to stick to black-and-white anti-aliasing at least.
Most of these issues exist on other platforms as well. Try running a QT or GTK app in Mac, or an opposing widget kit app on Gnome or KDE.
Things have certainly gotten better (similar to HiDPI support, multi-monitor, etc) as developers have standardized or learned the tools, but an individual app can choose to do it’s own bespoke rendering on any platform.
Fair, it's not a windows issue. I only use windows, so I've only experienced it on windows and I didn't want to overstate - but obviously that was poor wording on my part.
You should try the Dark Reader plugin that reverse all the colors and make the subpixel rendering of the web version of MS Word become BGR subpixel rendering. I know it because the text looked weird on my RGB display with the plugin on.
I was about to get a monitor that was too good to be true for the price. Turns out it was BGR. At the time, I didn't know what that meant. But the reviews said it was not good, so I avoided it.
I appreciate that reviewer every time I think about it.
