Description Telesto 2021-01-20 08:57:51 UTC 
Description:
Font rendering is different; tendency to get kind of blurred depending on zoom level

Steps to Reproduce:
1. Open the attached file
2. Compared this with say 6.2 rendering

Actual Results:
Dialog text & font rendered differently. I would say 6.2 is better (especially dialog text)

Nothing against 'bold' being more bold.. but at a whole doesn't read confortable

Expected Results:
Something like 6.2


Reproducible: Always

Screencast showing difference at 300%

This screencast only show difference.. the readability appears to be better (more bolder with 7.2) but in overall it's not

Looks like Skia issue (but would say it's present on OpenGL also to some extend). Skia made it simply more obvious
