Window does not fit in vertical smartphone screen
When playing a video on a Linux phone, Totem does not fit in the screen, meaning only the left side of the window/video is shown. This also hides every button on the right side of the window, like fullscreen, volume and the dropdown menu. A workaround is to rotate the screen 90 degrees. The Pinephone has a 720x1440 resolution, with the shell scaled 2x.
There is probably a reason for having a minimum window width, but it's detrimental to mobile users.
Distro: Mobian Unstable
Totem: 3.38.0 (the latest from Flathub)
