Microsoft’s new terminal application rendered text extremely slowly, like 10 minutes to cat 1gb of text slow.

Casey submitted a bug saying that it’s slow and should be much much faster.

Microsoft responded something like “text is hard … … phd dissertation on rendering text”

Casey made a terminal renderer with more features than Microsoft’s renderer in a weekend, it performed orders of magnitude faster, had zero optimization work performed and he jokingly (and hilariously) titled the video “a phd dissertation”.

Next, the excuse parade rolled in and came up with all manner of excuses as to why Muratoris renderer was so much faster, so he made a follow up video addressing the excuse parade, as well as containing some very minor optimization.

Also note that Casey’s implementation isn’t even as fast as things could be. His optimizations are minor.

It's nothing serious just microsoft engineers writing slow as shit code and reacting poorly to someone trying to help.
