Unified invalidation for repaint-only style change of layers (Closed)
DescriptionUnified invalidation for repaint-only style change of layers
There are 2 issues for repaint-only style changes of layers:
- repaintIncludingNonCompositingDescendants() called before style change
invalidate the old locations only;
- missing invalidation of the whole layer after style change.
Add RenderLayer::setShouldDoFullInvalidationIncludingNonCompositingDescendants()
and call it after style change. Then the old and new locations of the
layer including it's non-compositing descendants will be invalidated
during the next invalidateTreeIfNeeded().
Existing tests:
- Some duplicated invalidations are avoided
- Under repaints on transformation change are fixed:
