I see this on macOS 15.3 (176220.127.116.11.8) as well … Chrome and Safari. I guess it needs to be investigated, nothing obvious stands out. Can you please create a ticket Issues · playcanvas/engine · GitHub to keep track of it.
We just wanted to add some info on this, we noticed that with Safari 15.4 a lot of our PC projects suddenly stopped working
Eg. On this configurator, the object is rendered correctly only for the first frame, then if the user moves the object as it would normally do, nothing happens in the scene, the object doesn’t move or anything.
No embossing writing (we create it trough scripts once the scene is already rendered, when the end user picks some letters).
No errors related to PC in the console
We tought of an error processing input at first, but playing around with the inspector, we noticed that manually resizing the window, causes weird stuff to appear:
A pink background scene
The embossing writing magically pops out
Moving the object (orbit cam), only moves the writing but not the object
In the meantime, you can just turn off antialiasing for your project - this seems to solve it for us but also other webgl based engines. That’s what the workaround does as well, but only when when it detects browser 15.4
