I tweeted about this, but at Singmajesty’s request I am also posting on the forums.
It seems there was a change between Openfl 8.2.2 and Openfl 8.3 that caused issues with some of the component rendering in the Haxe port of minimalcomps when targeting HTML5.
To be honest, I’m not sure how serious this issue is given that the Minimalcomps library is at 0.9.2 and hasn’t updated in over a year, but I figured I should bring up the issue just in case.
Minimalcomps does not work right out of the box without slight modification. The minimalcomps.components.Component class uses an “invalidate()” function that works in Flash but runs into issues with the invalidate function in the Sprite super class when exporting to HTML5. For this reason, I had to rename the function in Component to invalidate2()
