Still the case with a self hosted server on the canary and stable Desktop App and on the official instance. This is one of the few features that still holds my community back from since we have quite a few ultra wide users. Would love to at the very least see the most common 21:9 aspect ratio as output with an automatically adjusting view port. Of course all aspect ratios being supported would be amazing.
