Bug report #16131
Identify and MapTip-Tool are not working correctly with displaced features
|Affected QGIS version:||3.4.1||Regression?:||No|

If a feature (point, line, polygon etc.) is rendered with an x/y-offset or by point displacement renderer, the "identify"-tool and the "maptip"-tool are not working at the displayed position/coordinates. They are only working for the original coordinates/position - which is not displayed.
It may be usefull to have this functions for the displaced feature-positions instead, because you can not know the original position without using an not displaced auxiliary layer.

I confirm that this issue also exists on QGIS 3.4.1 on Linux.
Using the new 'Import geotagged photos' tool combined with the HTML map tips (as described here https://nathanw.net/2012/08/05/html-map-tips-in-qgis/) makes QGIS an extremely nice way to browse geotagged images. Especially because you can put a 'file://' link in the HTML to open the images externally.
Using the Point Displacement style lets you see when you have multiple photos at the same point. However, the map tip only appears for the centre point, and only for one of the features. If it applied to the displaced point, it would be possible to view all images.
