I am having the same issue. Following this for a solution. Started yesterday.
mouse cursor invisible over pieces suddenly
I have backed out the latest windows 11 upgrade and chess.com is working again now. Seems related to a windows upgrade.

It's a windows issue. Happened to me after the latest update. It's also happening on a few other applications as well.

It is I think an issue from Windows only, bcz I've also started facing it after the recent update.
It's fine on lichess.org, but here it is extremely annoying.

From what I've been seeing, it's an update on the client end that's causing the problem. Staff are aware and looking to see if there's a way to fix it from the site code side of things
Hello,
I've encountered a problem today while playing on Chess.com using both Edge and Chrome browsers. Whenever I hover my mouse cursor over any chess piece during a match (this includes playing against the computer), the cursor disappears. This issue significantly hampers my ability to play fast-paced games like bullet or blitz, as it's difficult to see where I'm pointing.
Here's what I've tried so far:
Unfortunately, none of these steps have resolved the issue.
I'm reaching out to see if anyone has experienced a similar problem or has any suggestions on how to fix this. Additional technical details:
Operating System: Windows 11
Browser versions: Edge: Version 122.0.2365.30 | Chrome: Version 121.0.6167.185
Your advice and insights would be greatly appreciated. Thank you!
