Known issues

These are the known issues in terms of support for various browser capabilities. In future versions some of these might be resolved.

While this page contains known issues with implementations in Polypane, a majority of issues you could encounter are the result of specific website implementations, such as difficulty logging in to federated logins like SSO, rate-limited servers or non-standard navigation. We have collected these on a separate page, website issues you could encounter.

React Developer Tools need a reload

With the React developers tools installed when first opening the Chromium devtools you might not see the Components and Profiler tabs appear. To fix this, reload your page with the devtools open and they should appear.

Popups

Popups are allowed but they are not synced between panes.

requestPointerLock crashes Polypane

The requestPointerLock API is not supported in Polypane, and will crash the app if called. This is a known issue with Electron, and we are looking into it.

history.replaceState

Polypane's implementation of history.replaceState does not yet follow the specification and will add an entry into your history list.

Lost connection in Chromium devtools

Sometimes the Chromium devtools lose their connection to your pane, which will show itself as the elements panel no longer showing the correct DOM structure. When this happens, reloading the devtools re-establishes the connection. Click the reload button in the devtools toolbar to do this.

macOS visual artifacts

Sometimes macOS will display weird artifacts over the UI, this is a known GPU issue in the Chromium rendering engine. To work around this you can select "Disable Hardware Acceleration" in the "View" menu. Note that this does come with a performance cost, since rendering now happens purely in software.

Back/forward buttons on Logitech mouses don't work

Many Logitech mouses have a back/forward button, which need to be configured to work with Polypane on macOS and Windows (they are supported out-of-the-box on other operating systems). Follow these steps to configure Logitech mouses on mac-os.

Wayland support

Electron support for Wayland is turned on in Polypane, but not perfect. If you run into issues (in particular ones that do not appear in other Electron-based apps) let us know.
