Visible pixels / sharp edges on macOS Catalina
Hello there, I use Gimp 2.10.22, my OS is macOS Catalina 10.15.3.
The problem is I have just noticed that creating/saving and viewing text varies from the experience I made on my PC (my graphic editor was Gimp, too). After I put the text on the picture I can see a lot of ugly pixels on the edges (see 1). Fortunately, I still have pictures I made on my PC so you can compare this (see 2), they're not perfect but still smooth. Could you tell me what the reason is? As you can see I still don't see any sharp edges on my current Mac.
Update: I noticed that I can see the pixels in Preview app but if I open the same picture in the web browser, the visible pixels/sharp edges disappear. What should I do to change it? Now, I don't know if the picture has got bad quality, or if it's just my Mac that makes it so bizarr.
I don't upload the pictures because it makes no sense at the moment.
Regards, Andy
