== General == === How does Looking Glass work? ===
Please see the following video that covers this:

There are several reasons why this can happen, the most common is your capture resolution. At the time of this writing, the windows capture methods struggle to capture high resolutions under certain circumstances, as a general rule of thumb anything greater then 1200p (1920x1200) starts to suffer from performance issues.
Some titles do some strange things at early initialization that cause capture performance issues. One such title is the Unigine Valley benchmark where the capture rate is limited to 1/2 the actual rate. For an unknown reason to both myself and the Unigine developers a simple task switch (alt+tab) in and out resolves the issue. This is not a Looking Glass bug.
== I'm having mouse issues ==Mouse integration is not top priority right now. Consider passing through a hardware mouse. If you can't or won't... == Have you tried hitting Scroll Lock to toggle mouse capture mode? ==Disable guest mouse acceleration (see: Read me first!)Yes, sometimes the cursor position doesn't update until you click. It's a QEMU problem. See the points above. == Is my GPU supported? ===
Your guest GPU almost certainly supports DXGI. Use DxDiag to confirm that you have support for WDDM 1.2 or greater.
Where is the host application for Linux?
The "Windows host application" is actually the display server, which runs in the guest VM. The only thing that needs to run in your Linux host OS is the `looking-glass-client` application
== Mouse Issues ==
=== The mouse doesn't stay aligned with the host. ===
This is due to windows mouse acceleration, it can be disabled with the following registry magic:

Contrary to the title this works just fine on Windows 10
Some other things to try:
* Have you tried pressing Scroll Lock to toggle mouse capture mode?
* Try keeping the client window the same size as the guest's resolution.
=== The cursor position doesn't update until I click ===
Make sure you have removed the Virtual Tablet Device from the Virtual Machine. Due to the design of windows absolute pointing devices break applications/games that require cursor capture and as such Looking Glass does not support them.
