Zotero 7 experiences lag in pdf scrolling compared to Zotero 6 on a 2018 Mac Mini.

I am using Mac Mini 2018,
CPU: 3 GHz 6-Core Intel Core i5
GPU: Intel UHD Graphics 630 1536 MB
MacOS: 15.0.1 (24A348)

When using Zotero 7 to read PDFs, scrolling is extremely laggy, especially in dark mode (though it lags without dark mode as well). This issue doesn’t occur in Firefox or in Zotero 6.

My Zotero 7 setup has no plugins, and toggling layers.acceleration.disabled does not resolve the issue.

Update 10/29: I found that this issue is linked to CPU usage. With the same PDF and zoom level, Zotero 7 reaches up to 160% CPU usage when scrolling, while Firefox stays at around 40-50%. It appears Zotero 7 may have additional built-in plugins for PDF viewing compared to Firefox. Are there settings I can adjust to optimize this?

    I updated the original post: the issue seems to be related to CPU usage. Waiting on any solutions for this
