Description
The reproducer below uses plain Rectangles. More complex items like Buttons and TabButtons are also affected.
Code
import QtQuick Window { width: 800 height: 400 visible: true Row { padding: 5.5 spacing: 5.5 Repeater { model: 10 Rectangle { width: 80 height: 40 color: ptr.pressed ? "pink" : "silver" TapHandler { id: ptr } } } } }
Steps to reproduce
- Build and run the code above, using the software renderer
- linuxfb plugin, OR
- eglfs plugin + QuickWindow::setGraphicsApi(QSGRendererInterface::GraphicsApi::Software)
- Click/tap on each of the Rectangles
Outcomes
Everything looks fine at startup. But when a Rectangle changes colour, thin black lines might remain at edges.
The problem does not occur when using hardware rendering (eglfs plugin + OpenGL).
