Martin Lange bf9f995d86 app: recover from a lost GPU device in Present 
validateAndProcess recovers from gpu.ErrDeviceLost returned by Refresh
and frame, but returns it from Present to processFrame, which closes the
window. On Windows, DXGI usually reports a removed or reset device from
Present, after a driver reset (TDR), driver update, or GPU switch, so
programs exit in that situation.

Handle a lost device in Present like in the other paths. The frame is
already released to the client and can't be retried, so release the GPU
resources and schedule a new frame, which re-creates them.

Tested on Windows by making the D3D11 Present report a lost device.

Tags

Pre-1.0 tags are provided for reference only, and do not designate releases with ongoing support. Bugfixes will not be backported to older tags.

Tags follow semantic versioning. In particular, as the major version is zero:

  • breaking API or behavior changes will increment the minor version component.
  • non-breaking changes will increment the patch version component.
