<br>
I compiled OpenSceneGraph 3.6.1 on a recently formatted Windows 10 laptop with up-to-date drivers. <br>
When I tried to run osgViewer with cow.osg, the model and screen started to 'flicker':<br>

<br>
but interestingly, when I took a screenshot, everything looked alright:<br>

<br>
Previously, the laptop was running Linux and this problem didn't happen.<br>
Does anyone have an idea why this is happening?<br>
<br>
Thanks,<br>
