Blank widgets "lag" in drawer

[anon(646756)]

This really annoys me... When I'm scrolling through widgets in drawer, widgets image doesn't appear immedeatlly, but with the delay of about a second. Widgets images are blank for a second, then they appear. This happens especially when I scroll faster then usual.. I even removed some widgets with auto starts app, but the issue is still there.. I have a nexus 4 with a custom rom and kernel, but I know that many other phones have the same issue.. Please google, fix this in 4.3.
