Konva stops working on iPhone after three pages?

First time poster and extremely amateur website maker here.

I made this test site with Konva: https://snuck.in/test/pink

You can tap the square to go to the next page.

It works fine on an old iPhone 5 (iOS 10.3.4). I'm able to tap through endless pages.

When I try it on an iPhone 7 Plus (iOS 13.1.3), I can only tap through three pages and then they start coming up blank. I get the same result in any browser: Safari, Chrome, Firefox, Opera Touch.

Any idea why it would work for three pages and then quit?

Let me know if I can provide more information. Thanks a lot!

Solution

Looks like there is the issue with memory leaks in Safari. After several reloads it showed me that the memory is over. It didn't fully clear canvas from memory.

As a workaround you may try to make stage smaller and destroy it BEFORE reload:

box.on('click tap', () => {
  stage.width(1);
  stage.height(1);
  stage.destoy();
  location.href = 'pink';
})
