Component/s: Quick: Core Declarative QML
When running Qt that is statically linked, a simple GridView with accessible delegates becomes significantly slower on scrolling. This is not noticeable in dynamically linked qt.
This has been seen with static QT5.15.6 and QT 5.15.7 versions so far.
QML profiling gives the following after scrolling 60000 identical items in a gridview, the creation of the text visibly lags the grid view scrolling when there is accessibility in the delegate.
|Accessibility||Type||Details||Total Time||Mean Time||Calls|
Here is the QML code that was profiled (the accessibility was commented out for the one without accessibility)
