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.
For example, some of the slider bars look fine in 8.2.2, but no longer render properly in 8.3. In both versions the Window component doesn’t render properly, but on my work computer it would not render at all.
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.
