Hello I have tried to reproduce the issue with firefox 141.0a1(2025-06-02) on Windows 10 unfortunately I wasn't able to do so.
Could you please answer the following question in order to further investigate this issue?

1. Does this issue happen with a new profile? Here is a link on how to create one: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

To be honest, this is an ongoing issue for maybe 6 months or longer. I need to work with a few windows software and this is happening after awhile.
I deleted all Firefox profiles about 2 weeks ago, and it happened again. It happens under certain conditions.

I thought maybe it it was a windows issue or the other software but as soon as I closed the firefox problem resolved.

I'm sorry. I misunderstood the nature of the problem initially. Reverting to re-triage.

I notice that you are watching a video while this is happening. Does this only happen while watching videos?

It happens under certain conditions.

Do you know what these conditions are?
