Issue when doing fullsceen on 125% scaling

I am using a Lenovo s540 with Ubuntu 20.04 and I have disabled my NVIDIA GeForce MX250 GPU so that I can get a good fractional scale of 125 %.

This is because with my GPU enabled, 125 % scaling gets just too big. It is fine with it disabled, but when I make a YouTube video full screen with disabled GPU on 125 % scaling, it becomes something as this image shows:

Here is a screenshot with 100 % scaling:

My laptop is a 14 inch laptop and with the scaling set to 100 % I almost can't see stuff. I even tried tweaking the text scaling, but that way I have to tweak it for every application separately. Also Firefox doesn't adapt to it if you keep scaling to 100 % and text scaling to maybe 1.05.

I know that I can also change the font, but what I was looking for was a proper fix for this.

I had the same issue, and after searching everywhere, I found a way to solve this problem.

All I did was to set scaling to 100% and after that change some settings:

1. Go to Settings > Displays > Set scaling to 100% and you'd better disable Fractional Scaling.

2. Go to Settings > Universal Access & change the following options:

   • Large Text : Enabled
   • Cursor size : Medium

These settings mostly had the same effect as 125% Scaling for me.
