Slow performance in PDFViewer2 component when events fire.
For some reason my PDFViewer2 component is encountering some pretty significant performance issues and I'm not sure why. It seems that whenever an event is fired (mouseUp/mouseDown) there is a significant blocking function call that completely freezes the component for a second or two and then it will continue.
As you can imagine having the component freeze for seconds at a time any time the user clicks or even moves the mouse button for any reason is pretty unacceptable so I'm trying to figure out why this might be happening.
This is a screenshot of the performance graph from Chrome after trying to simply move an annotation shape. The function takes 1.34s to fully execute and during that time the entire component is unresponsive. This is just from trying to click/drag an annotation shape to a new position.
The PDF itself is not large at all. The documents are almost always less than 500kb and only a single page. The content itself is fairly simple as well, usually just an image with a basic pdfgrid containing some data. I create a new PDF using the PdfDocument class, insert an image, a pdfgrid with data, sometimes a hyperlink, and return a base64 string which is used as the DocumentPath for the viewer.
I do increase the page size of the PDF to be an A4 page size but really there isn't anything overly complex happening in my code.
Is there something simple that I could be missing? Maybe some listeners that aren't being disposed of maybe?
I'm using Dotnet 8.0.101 and all my Syncfusion package versions are 24.1.45.
