## Summary of the Pull Request ControlCore's _renderer (IRenderTarget) is allocated as std::unique_ptr, but is given to Terminal::CreateFromSettings as a reference. ControlCore::Close deallocates the _renderer, but if ThrottledFuncs are still scheduled to call ControlCore::UpdatePatternLocations it'll cause Terminal::UpdatePatterns to be called, which in turn ends up accessing the deallocated IRenderTarget reference and lead to a crash. A proper solution with shared pointers is nontrivial and should be attempted at a later point in time. This solution moves the teardown of the _renderer into ControlCore::~ControlCore, where we can be certain that no further strong references are held by ThrottledFuncs. ## PR Checklist * [x] Closes #9910 * [x] I work here * [x] Tests added/passed ## Validation Steps Performed The crash is a race condition and inherently hard to reproduce. During validation this PR didn't appear to introduce new crashes. |
