Hi, thank you for your feedback.

PhotoShow 4.90.0 includes a fix for an issue that, in rare cases, could lead to significant performance problems. If you haven't already, I'd recommend updating to the latest version and seeing whether the issue has been resolved.

If the issue persists, please feel free to reach out via email, GitHub, or the PhotoShow Discord community. If possible, include links to the specific pages where you notice the problem, along with any other details you think might be helpful. That will make it much easier to investigate and address the issue.

Thanks again for reporting it!
