Description Alexey Chernov 2011-02-20 22:55:37 UTC

Version:           unspecified (using KDE 4.6.0) 
OS:                Linux

Task Editor part is painted with stroking vertical and horizontal black lines when hovering the option with mouse (see the screenshot). I've tested it on ATI (radeon driver), Intel (both with 2D) and NVIDIA (proprietary driver) with 3D.

Reproducible: Always

Steps to Reproduce:
1. Open a task.
2. Move the mouse all over the form.
3. Notice black lines appearing and disappearing here and there.

Comment 1 Alexey Chernov 2011-02-20 22:58:22 UTC

The problem is in TaskEditor::paint function. It uses partial repainting to optimize the process but don't void the painter's pen (according to documentation it's QPalette::Text color which is black usually). So the boundaries of repainted areas are painted with black lines.
The patch with the fix is attached.
