It happened on Fedora Silverblue and OpenSUSE MicroOS.
A few days ago, the Chromium browsers (Flatpak Brave and Edge) on my HiDPI laptop suddenly looked blurry. After the investigation, I found
--ozone-platform-hint=auto that enabled native Wayland mode was the culprit. I enabled native Wayland mode for years and never had any problem before.
I’m wondering did some else also encounter the same issue? Would it be any recent runtime change that might cause the bug?
