The last time I saw this issue was yesterday on my Windows 10 PC. It is up to date with Windows updates, with Windows 10 Pro 22H2. Fwiw, I only ever see the issue in Firefox, and never in any other software on the system (in particular, Chrome does not have the issue). Not sure if it is a general Windows problem, but if it is, then only Firefox is seemingly affected.

The last time I saw this issue was yesterday on my Windows 10 PC. It is up to date with Windows updates, with Windows 10 Pro 22H2. When I test now, I don't see any issues, although the problem has not been particularly deterministic to happen. Fwiw, I only ever see the issue in Firefox, and never in any other software on the system (in particular, Chrome does not have the issue). Not sure if it is a general Windows problem, but if it is, then only Firefox is seemingly affected.
