We're really sorry about this, but we've recently been made aware that in rare circumstances, with some multi-display setups, an issue can occur which causes your screen to flicker. We're currently investigating this as a matter of high priority.

If you find you're experiencing screen flickering whilst using Portal, please email us at hello@portal.app Any additional information you may be able to provide would be great in helping us get to the bottom of the issue and arriving at a fix.

In the meantime, we'd recommend any customers with photosensitivities or photosensitive epilepsy to disable the Motion Desktop feature for now.
