Description:
In skia rendering mode, the default bold Chinese font will be displayed in green under specific page zoom. Many fonts also have this problem. I don’t know if it will appear in English. This problem has always existed since version 7.0-7.5. I hope it can be fixed.

Strangely, the video I record is always black. But the screenshot can clearly see that the text has changed color.

Probably because of the image compression, after uploading to Imgur, the green color is no longer visible, which is really strange.
