The render thread freed the overlays as soon as it exited, while the main thread could still be dispatching display server input callbacks that iterate them. Free the overlays in lg_shutdown instead, once the render thread has been joined and the display server has shut down. The overlays now outlive the renderer, so overlayFreeImage must not call into it; renderer deinitialization has already destroyed all textures along with the context.
Looking Glass
Looking Glass lets you use a Windows virtual machine from Linux with very low display and input latency. The current recommended setup uses the Looking Glass Indirect Display Driver (IDD) in the Windows guest and the Looking Glass Client on the Linux host.
- Project Website: https://looking-glass.io
- Documentation: https://looking-glass.io/docs
Start here
The Linux client is currently distributed as source code and must be built before it can be installed. The end-user guide covers the complete process:
- Build the Linux client.
- Configure shared memory for the virtual machine.
- Install the Looking Glass IDD in Windows.
- Install and run the client.
See the Looking Glass documentation for the current requirements and setup guide.
