Performance Issues with Multiple Tabs and PDF Navigation in Zotero

edited 16 days ago
When more than six tabs are open, there is noticeable lag in PDF files. Additionally, when navigating between duplicated tabs within the same window, the last page I left open often changes unexpectedly and reverts to its original position, disrupting the workflow.
I have opened the same file in multiple tabs, and while the same file is open in each tab, the page numbers being viewed are different. However, when navigating between these tabs, there is a sudden lag, and all the PDF tabs revert to the same page, disrupting my work.

    Zotero currently caches up to 5 tabs in memory, so if you view others, some tabs will be unloaded and may take a moment to reload when you return to them. We're planning to optimize this in future versions on systems with enough memory to keep many tabs loaded.

    I can reproduce the problem with the last-viewed page. It looks like, if you have duplicate tabs on different pages, and one of the tabs is unloaded (because you viewed 5 other tabs, including the duplicate), when you return to the tab it can change to the page from the other copy. We'll try to fix that.
