    Description

      The fix for QTBUG-115461 didn't fully fix the issue, it's still reproducible with QOpenGLWidget. I tried to patch Qt to force both QBackingStoreDefaultCompositor::createPerQuadData and QBackingStoreDefaultCompositor::updatePerQuadData to always use m_samplerLinear, the issue disappears then.
