Windows 10 &11 Intel Iris Xe and Microsoft apps conflicts and poor performance

Occasional Contributor

I wrote this as a reply to a user in another post, but I believe this is an issue by itself as I haven't found information on this to date.

I have an Acer Aspire A515-56 (11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz 2.42 GHz) with 20 GB RAM.

I've had small issues with every Intel Iris Xe driver 27.20 version up to its latest 27.20.100.9466 version (mainly random Autocad crashes, but nothing really serious)

BUT newest versions of the driver, 30.0.100.xxx, including the latest 30.0.101.1069, simply don't work with Microsoft programs at all. Everything else works ok, including Windows UI, Firefox, AutoCAD,  and even WSLg Linux apps, BUT both Edge and Microsoft 365 v2019 (namely Outlook, Word and Excel) become extremely laggy, to the point of being unusable. Experimenting with Office apps "Disable hardware acceleration" solves the issue in Edge, Outlook and Excel, but as my Word version does not have that option available for some unknow reason, it can't be fixed.

As said, all other programs, including games, work just well with either driver. This just confirms the issue is a conclict between Iris Xe driver and the way Microsoft implemented hardware acceleration in Edge and Office apps.

Reverting back to driver v27.20.100.9466 solves all the aforementioned issues.
