I would encourage you to try SteamVR beta. It often has less issues than the stable version
From KNOWN ISSUES:
The VR status window isn't currently aware of direct mode being enabled or not, so the "enable direct mode" and "disable direct mode" buttons should not be used; direct mode is automatically enabled where supported
Most likely you already have Direct Mode enabled.
To check it, open your display properties where you can see monitors list.
If VIVE is in Extended Mode, it should be shown there as another monitor.
If it is not there, it is in Direct Mode.
That image corruption or whatever was fixed in a Steam client update months ago. (At least on my machine.)
Nothing extracted yet.

I expected to enable direct mode. Instead, enabling direct mode causes SteamVR to either crash or restart, either way not enabling direct mode. When doing so it also messes up the steam client: https://i.imgur.com/dRke9Nr.png
