Not sure this is a bug, but I would like to close the other two that deals with that. So, this function is only called from PluginProxy like: m_pluginBackingStore->paint(*graphicsContext, contentsScaleFactor(), IntPoint(), pluginBounds()); but the contensScaleFactor is only changing from 1 to any other value on Mac, like: void PluginView::setDeviceScaleFactor(float scaleFactor) { if (!m_isInitialized || !m_plugin) return; m_plugin->contentsScaleFactorChanged(scaleFactor); } but this is a Mac only method right now. So we don't need to handle the "!= 1" case currently.

I'm implementing it for Qt in bug 98518.
