Description Tyson Tan 2023-01-10 02:08:57 UTC
In the most recent nightly build for Android (2023-01-09) , Krita has severe slowdowns across the UI. Including but not limited to:
1) Hovering across menu items;
2) Creating a selection by dragging a rectangle;
3) Cropping by dragging a rectangle.

Only the Freehand Brush tool seems to be unaffected.

Reverting to the version 22dd109 before the recent 3 continuous failed building attempts and the slowdowns stopped.

Yes... Sharaf is aware: we discussed this yesterday. It's because we updated to Qt 5.15, and that is causing regressions.

Android: Update Qt GIT_TAG

This fixes:

1. Issue on ChromeOS where mouse events were previously passed down as
Touch Events but now are correctly sent as QMouseEvents.

2. JNI references leak causing app to crash on older devices.

3. Slow down as described in bug 464081.
