'Save this image with XCF file with better but slower compression . .': unintelligible English
GIMP version: 2.10
Operating System: Windows 8.1
Package: Installer.
Description of the bug
In the file dialogue, one sees, 'Save this image with XCF file with better but slower compression'. That text is fine. The text that follows it is not. For, in that subsequent text:
(1) the comma is ungrammatical; (2) 'The image uses' should be (I think), 'This format uses'.
Indeed the whole sentence is very hard to understand (and the next sentence has its problems too). I would propose an alternative formulation of the sentence. However, I find myself unable to do that, because I do not have enough of a grasp of the intended meaning.
