If we set the bottom right coordinate to the outer edge of the pixel we might end up not drawing the fade effect on all of the pixels. This could for example happen if one logical pixel (clutter stage pixel) consists of more than one physical pixel. https://bugzilla.gnome.org/show_bug.cgi?id=765011 --- diff --git a/src/st/st-scroll-view-fade.c b/src/st/st-scroll-view-fade.c index 37f44c42c..3942cbcf0 100644 --- a/src/st/st-scroll-view-fade.c +++ b/src/st/st-scroll-view-fade.c @@ -110,8 +110,8 @@ st_scroll_view_fade_paint_target (ClutterOffscreenEffect *effect) */ fade_area_topleft[0] = content_box.x1 + (verts[0].x - paint_box.x1); fade_area_topleft[1] = content_box.y1 + (verts[0].y - paint_box.y1); - fade_area_bottomright[0] = content_box.x2 + (verts[3].x - paint_box.x2); - fade_area_bottomright[1] = content_box.y2 + (verts[3].y - paint_box.y2); + fade_area_bottomright[0] = content_box.x2 + (verts[3].x - paint_box.x2) + 1; + fade_area_bottomright[1] = content_box.y2 + (verts[3].y - paint_box.y2) + 1; g_object_get (ST_SCROLL_VIEW (self->actor), "hscrollbar-visible", &h_scroll_visible,
