Hi, I hope someone can help me out with some repaint issues in IE10 because I am a bit stuck here
Within my application (just upgraded to the 3.0.1 Qooxdoo version) I have embedded a "qx.ui.embed.Html" containing a Silverlight app (I know...). When placing a qx.window containing elements that can get mouse focus over this SL app and moving the mouse over such an element (e.g. button or date chooser) all elements but this single one overlapping with the SL app are no longer shown. Attached a small preview of such a scenario where the mouse was over the date chooser that is showing its text. I noticed that when I move the mouse to the top of the window (which is resizable) the MResizable mixin sets a resize cursor which applies this cursor to all child widgets which then get flushed (qx.html.Element.flush) and everything is displayed again. As a test I implemented a "mousemove" event on all focusable widgets in my window and adjusted the window's cursor there. This had no effect. Only after calling qx.html.Element.flush() from that same hack all controls were properly shown again. I am wondering what is going wrong here. Off course this has something to do with IE10 and Silverlight (everything works fine in IE9 + IE11) but it also seems that something goes wrong updating styles when widgets get the mouse focus. Maybe there is an optimization somewhere that doesn't update styles in all cases? I hope anyone has an idea cause it's driving me nuts ;-) Best regards, Jeroen
