Some dialogs are blurry on HiDPI devices

Some dialogs are scaling text instead of using hiDPI properly. The publish calendar and the link attachment dialog are blurry when they should not be.

See attached file and note the difference between the two words marked "Publish"

Welcome to Trac, @stuartsweet, and thank you for the report!

As noted during the previous `#accessibility` scrub, this should ideally be reported upstream in Gutenberg, where it can more readily be addressed. It was also noted that this isn't an a11y concern per se, so I've removed that focus for now.

Once reported in Gutenberg, this ticket can be closed with reported-upstream.

Reproduction Report

I was also able to reproduce this even if I don't have hiDPI monitor by changing zoom. Depending on the zoom and current calculated position of the modal, it can vary. Especially blurry: zoom 110%, 150%


Hardware: Asus ROG G750JS
OS: Windows NT 10.0 AMD64
Display: 1920x1980
Server: nginx/1.16.0
PHP: 7.4.3
WordPress: 6.2
Theme: twentytwentytwo
Plugins: no active plugins

Actual results

✅ Google Chrome 111
❌ Firefox 111 (here zoomed modal menus look fine)
✅ Microsoft Edge 112
✅ Avast Secure Browser 112


It looks like this is issue with rendering abilities of the browser layout engine and caused by transform -> translate style params.
And triple scrollbar looks… overwhelming.
