2.1.5 bug I have not with 2.1.4:
-Very slow when modify the fonts or texts options.
-Text become very blur after the page of the refresh (= only the page who have the refresh is ok).
Now I must use refresh on every page... before a refresh every 6 pages was ok.
-When I open the read menu, choose a option who open a windows, and close it... the text who was under the window is more dark, bold and blur.
-Freeze many sec when I change of chapter.
Have no one of this problem when I was in 2.1.4.
