Toggle layer visibility bug?

I’m experiencing a very strange and specific bug with the Layers panel visibility toggle.

What happens

1. I click the eye icon on any layer to hide it, this works normally.
2. After that single click, if I simply hover the mouse over other layer names (not on their eye icons), those layers also turn off one by one.
3. The only way to stop it is to click anywhere on the screen.
4. It feels like the “click and drag to multi-toggle visibility” feature is getting stuck in the “button still held down” state after a normal click.

It happens in every file (not file-specific).

A friend checked on his machine and does not have this issue, so it appears to be local to my setup.

When it started

I was working normally. I left the computer running for about 2 hours (no updates, no crashes, nothing unusual). When I returned, the bug was there and has stayed ever since.

What I’ve already tried

• Restarted the PC
• Cleared Figma cache
• Tested in different browsers + Incognito
• Unplugged my mouse, launchpad and XP-Pen tablet
• Confirmed it’s not Windows ClickLock

Nothing has fixed it.

I recorded a short video that clearly shows the behavior.

Has anyone else run into something like this? Any ideas what could cause the Layers panel to get stuck in multi-toggle mode after a normal click?
