Why have my Gnucash reports stopped working

Question

For some reason Gnucash Reports no longer work on my Ubuntu 20.04 Flatpack installation. They were working last week. After setting report parameters I get a blank screen. No Error message. After consulting Gnu cash support I have found that if I export the "blank screen" to an .html file I can open the report with firefox. I think it's something to do with Flatpack,an upgrade to Firefox, a ubuntu update,and new file paths but I am not technically proficient enough to find and correct them

This happened to me today, and appears to be an issue with flatpak updates.

Workaround for me was to launch from the terminal:

WEBKIT_DISABLE_COMPOSITING_MODE=1 flatpak run org.gnucash.GnuCash

Edited to add: Better solution from the bug reports is to run flatpak update first. For me, this updated Nvidia drivers and solves the issue without needing to run through terminal.
