Windows 10 Insider Preview Build 16237 was released to Insiders in the Fast ring on Friday, and one of the more significant changes regards DPI scaling: users will no longer have to log out to fix blurry apps, which should be much appreciated by those who frequently dock and undock their devices. Small changes have also been made to the GPU performance tracker in Task Manager: the UI layout has been tweaked, and the DirectX version and physical location of your GPU is now listed.
…we’ve changed the way that Windows provides DPI-related information to these applications such that each time one of these applications starts, they’ll get updated data from Windows. This means that for these applications, you simply re-launch them in order for them to render correctly if they’re blurry. While this isn’t what we all want: having these applications render crisply all the time, we feel that it’s a lot less painful to relaunch apps instead of having to close out of all apps and going through a log-out/log-in cycles.
