Chrome menus too slow after enabling fractional scaling in Ubuntu 20.04

A few weeks ago I set up fractional scaling to 125% in Ubuntu 20.04.

After that I noticed that some of the menus in chrome are too slow. When I disable fractional scaling the speed goes back to normal.

I tried to search but so far couldn't find anyone with the same problem, nor any other application that has the same issue (firefox works fine).

My computer is an X1 carbon 8th gen, with Intel UHD Graphics.

I meet the same problem. One possible solution for me is to disable the hardware acceleration of Chrome:

1. Toggle off: Settings -> System -> "Use hardware acceleration when available"
2. Relaunch Chrome.

Tested and works on Ubuntu 20.04 and Chrome Version 86.0.4240.111.
