Actually I don't know when it existed, but recently after changing some themes, the editing area has a strange light color block.
It's neither a blank string nor a blank line break, it 'jumps' with the area you're editing. This is quite annoying and I have not been able to find a real answer to this problem.
In some cases, changing the theme occasionally helps, but it mostly doesn't work, and I don't think that's a good idea because those light blocks are always stubbornly present, can anyone help?
P.S I hope I can express the problem precisely enough, I'm attaching a screenshot to point out the so-called 'light blocks'.
Thanks for any help!
