We are experiencing some weird and random flashing (hiding/showing) of scroll bars in windows and canvases, as they're being continuously redrawn in a an infinite loop. This happens in certain browsers (IE9, Chrome) when we bring up certain windows in our app . At this point we can't really figure out what's triggering this behavior, and we're stuck on how to address it, and so I am posting this question here, along with a standalone test case hoping for some feedback, and directions on how to best handle these situations. This particular test case I am providing below reproduces this behavior on IE9 only (Chrome and FF work fine). We have many other cases where the window exhibits this behavior on other browsers. So I guess I have two questions:
1) Is what am experiencing in this test case a bug in SmartGWT?
2) Given that I am also seeing this behavior in other dialogs that are different than this one (i.e. smaller than the main canvas, but contain multiple forms in a SectionStack, is the issue there related to this one? What's the best way to handle issues like these?
Problem happens in SmartGWT4.1p, and 5.1d(Build 2015-05-14), and GWT2.6.1
Any help is greatly appreciated.

Code:
public class MainEntryPoint implements EntryPoint { /** * Creates a new instance of MainEntryPoint */ public MainEntryPoint() { } /** * The entry point method, called automatically by loading a module * that declares an implementing class as an entry-point */ public void onModuleLoad() { final VLayout layout = new VLayout(); layout.setWidth("100%"); layout.setHeight("100%"); final TestWindow win = new TestWindow(); win.setVisible(false); IButton openBtn = new IButton("Open Window"); openBtn.addClickHandler(new ClickHandler() { public void onClick(ClickEvent event) { win.moveTo(layout.getPageLeft(), layout.getPageTop()); win.resizeTo(layout.getInnerWidth(), layout.getInnerHeight() ); win.show(); } }); layout.addResizedHandler(new ResizedHandler() { public void onResized(ResizedEvent event) { win.resizeTo(layout.getInnerWidth(), layout.getInnerHeight()); } }); HLayout hl1 = new HLayout(); hl1.setWidth100(); hl1.setLayoutRightMargin(5); hl1.addMember(openBtn); layout.addMember(hl1); layout.draw(); } }
Code:
public class TestWindow extends Window { public TestWindow() { setIsModal(true); setShowModalMask(true); setModalMaskOpacity(40); setCanDragReposition(false); setBorder("0px"); setShowEdges(false); setShowHeader(false); setShowShadow(true); setShadowSoftness(10); setShadowOffset(5); ImgButton closeButton = new ImgButton(); closeButton.setSrc("[SKIN]/headerIcons/close.png"); closeButton.setSize(16); closeButton.setShowFocused(false); closeButton.setShowDown(false); closeButton.addClickHandler(new ClickHandler() { public void onClick(ClickEvent event) { hide(); } }); HLayout hl = new HLayout(); hl.setWidth100(); hl.setAutoHeight(); hl.setAlign(Alignment.RIGHT); hl.addMember(closeButton); addItem(hl); } }
