Half of mirrored screen is black

[ydoc14]

I am using scrcpy inside a debian bullseye crouton chroot, and it works great, except that large portions of the mirrored screen will be black. Different portions of the screen will turn black when navigating around the phone, on any app. It goes away by disabling compositing on xfce window manager tweaks, but then there is significant lag. Enabling compositing removes the lag, but then makes the choppy blackness start again. Please see the screenshot below.

I forgot to mention that this problem only happens when running scrcpy in --window-borderless mode.

You should report the problem to SDL (the library scrcpy is using).
