I was able to correct this issue by changing the HDR settings just for Brave. Open the Properties of your brave launcher from the start menu by searching brave, r-clicking, and select Open File Location. Then you r-click Brave and select Properties. Go the Compatibility Settings tab and select the Button at the bottom that says High DPI settings. The of the story is the attached picture. Just check both of those boxes and restart your browser.
@Kimchi you’ve been silent a bit. Wanted to tag to see if you’re having issues still. And if still an issue, have you been able to test like jcyree mentioned just above?
Never a good comparison. Would more or less need to know if you have the issue with Chrome, so as to find out if it’s a Chromium issue or more downstream to be Brave specific.
Beyond that usually would be good to find things like if the issue persists in private window, if you’ve tried in a new profile, etc.
