Is there a solution to arbitrarily resizing the canvas in Google Chrome?

Question

Canvas

Good afternoon!
There is an animation in HTML5. In Chrome on Windows XP SP3, the sizes spontaneously increase, in other browsers everything is in order. On Windows 10, Chrome behaves correctly. If you view the banner on a local machine, the dimensions are the same as indicated, but when uploaded to the hosting, the size changes from 990 to 1086 pixels in width, and from 250 to 275 in height. It would be possible to ignore XP, but the customer, who has this particular OS (and he accepts work in Chrome), does not want to delve into the essence of the issue. The animation developer is third-party, I just need to hang a banner on the site.

Answer 1

Maybe the customer in Chrome has a trite zoom turned on? Let him try pressing Ctrl+0.
