Mouse fixed at top left in Firefox for Android about squeakjs

[codefrau]

Works for me – both on 106 and 108. I tried various images on squeak.js.org.

Where exactly do you see the problem?

So I tried debugging with ADB. First of all, after adding a breakpoint for canvas.ontouchstart, touch.x and touch.y display correctly, and pinching for zoom behaves correctly as well, but the mouse remains stuck on the top left corner. I tried disabling addons and Enhanced Tracking Protection, but the behavior persisted. I then tried to create a clean install of Firefox 108.1.0 leaving all of the default settings (except for remote debugging) and going straight into squeak.js.org, and it also did not work.

The device is a Poco F3 running LineageOS for microG, build 19-20221201-microG-alioth.

Oh it's a phone! I tried with Firefox's touch emulation on desktop, and that does work.

The touch logic is pretty simple:

SqueakJS/squeak.js

Line 459 in a947f96

function touchToMouse(evt) {

Maybe add some debug logging?
