Fixes #10640
Description
Marks
AdornerLayerdirty when any of theAdornersis dirty and forces a measure pass so that the position is updated.Due to the aggressive performance optimization to only re-render when size/position changes (including transforms),
a case such as this has been overlooked so the position of the respective Adorner's is wrong while all flags are correct.
This could have been workarounded via synchronous
UpdateLayoutpass called by the user or invoking visual re-invalidation but due to its asynchronous nature this would only work the second time around.I have also removed the redundant assigment of cached
RenderSize/Transformand in-lined the two calls instead.This shall not add any unnecessary overhead according to my testing.
Customer Impact
If the fix is not taken, customers will continue to observe unwanted behaviour and will be required to use computionally expensive and synchronous updates to receive the correct position for Adorners upon adorned
UIElementchanges.Regression
Not according to my tests, this seems to be present both on
.NET CoreandNETFX.Testing
Local build, repro tests from #10640, tests with adorners.
Risk
Medium, it would be beneficial to test more real-life examples of adorners.
