Main issue is memory usage. Running KDE+Kate - http://vps2.etotheipiplusone.com:30176/redmine/emscripten-qt-examples/kate/kate.html http://vps2.etotheipiplusone.com:30176/redmine/emscripten-qt... - uses 1793MB (htop VIRT), 416MB (Chrome task manager). (Oh, and the renderer process wasn't hosting any other tabs.) Second main issue is speed. qsterix isn't as memory-heavy but runs all Tetris game code inside KDE JavascriptCore, which as part of the KDE/Emscripten build is transpiled to JS. In other words, http://vps2.etotheipiplusone.com:30176/redmine/emscripten-qt-examples/qstetrix.html http://vps2.etotheipiplusone.com:30176/redmine/emscripten-qt... is JavaScript inside JavaScript, and on my reasonable-but-not-last-week-new i3 box, I experience a small pause that I can't explain when I hit the spacebar to drop a block. Half of me wants to warn everyone from opening these on their phones or tablets, the other half wants to know how badly everything crashes. :P Note: I tried opening the Kate demo a week or so ago on a marginally older version of Chrome, and the download phase hung. It worked this time though.
