Same pointer issue for me except that I also notice the fonts in the browser itself are much larger as well (they appear to be increased by the same amount as the cursor). To be clear, the content font of a web page is as expected but, for example, the URL that shows up at the bottom when you mouse over a link is significantly larger.
Ubuntu 22.04.5 LTS and Breve Versión 1.77.97 Chromium: 135.0.7049.84 (Build oficial) (64 bits, same issue.
Update to v1.77.100 same issue…It would be kind and appropriate from the developers if they would provide a definitive solution in the next update!
Lubuntu 24.04 LTS Brave Version 1.77.100 Chromium: 135.0.7049.100 (Official Build) (64-bit).
Confirmed.
Workaround = Force the size in environment with
XCURSOR_SIZE=32
