[2.0.73] Font aliasing on UI buttons abnormal in fullscreen

[khjxiaogu]

I'm using a 2560x1440(2k) display. Everytime I switch to fullscreen mode, text on buttons seems weird as they seems cropped incorrectly. Restarting the game does nothing on this issue.

However, other text seems normal:

And it become worse when Chinese language is selected:

Hmm, to me all the graphics look weirdly over sharpened or something,
Do you have any Graphics overlay, or upscaling technology active?
Anything strange in Nvidia control panel?
Could you try in the Nvidia App (if you have it installed) resetting the config for Factorio to all defaults?

This seems to be happening to me too. It started when I updated the game to 2.0.72 from some much older version.

Just updated my drivers to the latest and it doesn't help.

Nothing weird in the graphics settings either.

It all looked fine until I updated to 2.0.72 and 2.0.73 from some unknown much older version of Space Age.

Anything else we can do to debug this?

What is your UI scale set to in Windows? right click the desktop -> display settings

[coffee_fiend]

Mine is set to 100%
But the game wants it to be 200%. But that makes the interface way too big for me to enjoy.
I didn't used to have the font issue at these settings though. So that shouldn't really be the issue.

Do you have any Graphics overlay, or upscaling technology active?

None. I play Factorio raw rather than through say steam with its overlay.

Anything strange in Nvidia control panel?

Nothing I see as strange.

Could you try in the Nvidia App (if you have it installed) resetting the config for Factorio to all defaults?

The Nvidia app doesn't even list Factorio for me. I guess I could add it and try but I really doubt that will help.

and....
You were right!

I didn't have it in the nvidia app at all. So I added it and it defaulted to some weird 85% scaling value. So I turned off scaling there in the brand new entry and lo and behold it looks good again.
It was setting the scaing to "85% (3482 x 1836)"

Just to be thorough I tried to re-enable that setting and it definitely causes the problem.

Just to be infuriating though the Nvidia app then tells me it can optimize the game settings and when it does it "TURNS OFF SCALING!"
Which never should have been on! Weird

Seriously what is up with that? Why would Nvidia do that that to a game it doesn't even have listed?

But regardless that did the job for me at least.

Now we just need to see if it helps khjxiaogu.
