Display settings allow you to use hardware-accelerated scaling to improve the speed of playback in Flash Player.
There might be compatibility issues with older hardware and drivers.
(See Flash Player system requirements.) With older versions of Flash Player, you should not see dramatic changes as the player reverts from hardware-accelerated scaling back to software scaling.
If you have display problems with Flash Player, such as poor picture quality or slow display times, deselect Enable Hardware Acceleration in the Display panel.
This should eliminate hardware or driver compatibility problems with Flash Player.
Flash Player then uses software to scale and display the content.
Windows 10 received a couple of updates as part of this month's Patch Tuesday rollout, so insiders running build 9926 of the technical preview are strongly recommended to deploy both of them as soon as possible.
One of these two releases is an update designed to fix vulnerabilities in Adobe Flash Player in Internet Explorer, as Microsoft is now manually patching any security flaws that are found in Adobe's software and also affecting its in-house browser.
This approach was first implemented into Windows 8 and Internet Explorer 10 and then adopted for Internet Explorer 11 as well, as Microsoft wants to make it easier for users to patch their applications and thus remain secure while browsing the web.
Today's security update is aimed not only at Windows 10 Technical Preview build 9926 but also at all the other versions of Windows that are still supported by the company, including Windows 7 and Windows 8.1, so just check Windows Update to make sure that you deploy it as soon as possible.
The second update that Microsoft rolled out today comes to address a bug in Windows 10 Technical Preview build 9926 that does not allow users to update their computers to a future build of the operating system.
The same bug might exist in older builds as well, but 9926 is the only one getting it through Windows Update, so make sure that you deploy it in order to get the upcoming builds as soon as they're released.
