STR: 1. Open https://news.mynavi.jp/list/headline/digital/pc/ 2. Move mouse pointer on the article title AR: The title(area) is zoomed and text font shape shifted just after transform(or within transform?). ER: No font shifted. Smooth zooming. Simplified reproducible html, <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <style> div:hover { transform: scale(1.05); } div { transition: transform .2s ease; } </style> </head> <body> <div>ASUS、22時間の連続駆動が可能なSnapdragon 835搭載2in1</div> </body> </html>
I guess this is referring to the text being rendered with grayscale AA during the transition; then after the transition is complete, it pops back to subpixel-AA rendering, which gives a slightly jarring effect. It's only slightly noticeable for me on macOS, but I can imagine it may be more visible for some people on Windows or Linux, depending on font rendering preferences.
