I am also having this issue. Can someone help?
Please see the image of the Power BI table, which is clear, but the Power App text is fuzzy.
People using this say it hurts their eyes, which is now a health and safety issue. 😅
I think I found the issue In PowerBI. When you get to 100% zoom, the PowerApp is clear.
Then, for every odd number you go up it is fuzzy, 100% clear, 110% fuzzy, 120% clear, 130% fuzzy...
The problem is the PowerBI page at 100% doesn't fit the full screen, and 120% is bigger than the screen.
So there is something wrong when you zoom in on the Power BI page that needs to be fixed.
This is on both desktop and web.
