Basically something as simple as ms-write with a speller would do. I don't want an office-like suite, and Abiword for the past year in arch/manjaro/artix does not work. The screen flickers when the mouse curson is in the text box. When I click outside the box it does not flicker but then I can't write. Once it clicks in the text area it flickers the write area at about 40-60hz
Not just arch based distros, even ubuntu and debian have the same issue with abiword.
