* claim: #4172 * GPU: a lost device stops drawing instead of crashing (#4172) After the driver resets the GPU (Windows TDR), the first queue write to meet the lost device panicked inside wgpu-core (PendingWrites::activate unwrapping DeviceError::Lost). Nothing watched the device for its loss. - egui-wgpu: RenderState::device_lost (DeviceLost) is set by the device's lost callback. The painter draws nothing on a lost device, and before a frame's uploads it submits nothing (DeviceLost::probe), so a loss the driver reports is found by that submission instead of the first write. - Pictures (thumbnails of saves, ui.render) watch the same flag: on a lost device the capturer refuses with GpuError::DeviceLost without touching it, and the picture comes from the CPU rasterizer. Headless capturers watch their own devices. - The app, seeing the loss, closes keeping unsaved changes for recovery (as a forced quit does) and starts again; the new start says what happened. A second loss within ten minutes starts on the software renderer. The loss is noted in the crash journal.
