--- Comment #54 from خالد حسني <kha...@aliftype.com> --- (In reply to Patrick Luby from comment #53) > I think that I have narrowed down this bug to drawing 24 bit bitmaps that > have an 8 bit alpha bitmap in SkiaSalGraphicsImpl::drawAlphaBitmap(). By > default, that method calls SkiaSalGraphicsImpl::mergeCacheBitmaps() which > combines the 24 bitand the alpha bitmaps into a single bitmap.

No difference or messages reported for me. I also don’t think the issue is limited to images, even the thumbnails in the start center have their white color turned into yellow. -- You are receiving this mail because: You are the assignee for the bug.
