Strange Screen Refresh Rate

XiaoluoFoxington replied
XiaoluoFoxington

Hello, I encountered an issue when using Firefox for Android. My device supports a 120Hz refresh rate, but in my Firefox for Android, only the browser UI runs at 120Hz while the web content runs at 60Hz.

Interestingly, when the menu is opened, even though the web content is covered by the menu, its refresh rate is shown to have increased to 120Hz. Then, after the menu is closed, the refresh rate reverts back.

It’s not just the menu. Any non‑web‑canvas element displayed in the foreground causes the same behavior, such as radio buttons, the system notification shade, or even pop‑up windows.
