GDK_SCALE leads to blurry text in hex pane while other text is fine

[schrmh]

This is with GDK_SCALE=4 wxHexEditor but it happens at any value over 1, however it is a bit less noticeable with smaller values

(Unrelated: Yes, I haven't figured out how to apply dark theme)

Himm. This probably because of hex panel is indeed painted picture that created from wxHexEditor.
So it's scale as a picture. Don't know if there a way to fix it.
