Description Yousuf Philips (jay) (retired) 2025-07-21 21:06:47 UTC 
Description:
I tried to open a 180+ page document and writer hangs for over 10 minutes, so i killed the process. I reduced the document to only the first 20 pages and it still hangs for over 10 minutes. I was able to reduce the pages to a single page and still result in hang.

Steps to Reproduce:
1. open document

Actual Results:
UI hangs for over 10 minutes

Expected Results:
document should appear to be browsed


Reproducible: Always

found a second 1-page that also caused the hang, though not sure if it is due to the same issue or not

Comment 4 Yousuf Philips (jay) (retired) 2025-07-21 22:31:12 UTC 
Both attached docs opened fine in my older version, so its a regression of some kind that should be tracked down.
