Age-old RPG maker bug occurring on certain systems.
In the game folder, navigate to and open up the file named "rpg_core.js"
Its relative path in the game folder should be: \www\js\rpg_core.js
Open it up in any old text editor, then find this exact portion (just CTRL+F "this._skipCount ===" or "Graphics.render" , or go to line 1872)
Code:
1871 Graphics.render = function(stage) {
1872 if (this._skipCount === 0) {
1873 var startTime = Date.now();
1874 if (stage) {
1875 this._renderer.render(stage);
1876 if (this._renderer.gl && this._renderer.gl.flush) {
1877 this._renderer.gl.flush();
1878 }
1879 }
Change the operators on line 1872 from "===" to "<=".
from:
if (this._skipCount
=== 0) {
to:
if (this._skipCount
<= 0) {
Save the file and try running the game - the screen image should no longer freeze with audio and game logic continuing.
