I’ve been using Google Chrome and Brave on wayland with ozone set to auto for the last 6 months. Today it’s behaving unexpectedly. Instead of the window pixel density increasing to match the desktop the entire window has scaled up, with the pixel density being lower than when ozone is turned off.
I have the same issue, also running on Intel Iris Xe. Yes, it seems an issue with chromium based browsers, I use Brave as default browser and it’s not rendering correctly. I have found a workaround, passing the -use-gl=egl argument, the browser works fine.
brave-browser -use-gl=egl
I haven’t tested in other chromium based browser, but I guess it should work fine as well.
