Recording pause shortcut
Priority: ➖ Normal — Schedule the Linux export and global recording shortcut changes because they affect core rendering reliability and recording controls across the desktop app. Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The recording pause shortcut does not work on macOS, and destroyed renderers may retain large staging resources. These issues should be resolved before merge. Sequence Diagram(s)sequenceDiagram

Hey! I've also got an open PR for this bug (#908) — our approaches look complementary rather than competing. One data point that might help your work: in my testing on Linux (Hyprland/Wayland, Electron 43.1.0, AMD RADV), the crash happens on the first rendered frame ( My PR keeps WebGPU as the default and adds an automatic one-shot WebGL retry when a render-stage failure occurs ( There's some textual overlap in |

Summary
Verification
The Linux WebGPU failure was caused by Electron requesting a device with a 16-texture per-stage limit while Pixi generated a 32-texture batch pipeline; the _resourceType exception was a downstream symptom.
