Description

Phaser Version 3.60 - Chrome Version 113.0.5672.126
CANVAS MODE

Hello,

It seems a spine Object starts to follow the camera when you set the camera following a character AND you set a rotation on the camera.
I reproduced the error here (I did not try to fix it ).

Work normally with WEBGL but not with CANVAS.

Move the cursor keys : the spine starts moving although it should be in fixed position like the background.
If you disable the rotation of the cam, the spine does not move.

Research direction

Start with the linked CodePen reproduction and compare the spine object's position in CANVAS and WEBGL while the camera follows a character with rotation enabled. Trace the Canvas rendering path for camera transforms, then verify that the spine remains fixed relative to the background when moving with camera rotation, without regressing the WEBGL behavior.
