Heads up: a second but very small patch for Mega Man Legacy Collection went live on Steam yesterday. According to the change log, it fixes "an issue which caused text and some textures to render as solid blocks of color." This minor annoyance is not an issue on home consoles, so no worries there.
Hopefully Capcom will roll out similar fixes over time for some of the other prevalent issues on PC. While the March update was a welcome addition, many users continue to cite performance issues.
