Is Pyxel really working properly on Linux?
Finally I setup the test environment for Ubuntu and started trying to run Pyxel by myself,
and I found if I install Pyxel in the "standard way" like this:
`sudo apt install python3-pip libglfw3 libportaudio2`
`sudo pip3 install pyxel`
as a result, Pyxel's rendering doen't work correctly (probably because of glfw version) and sound is not played correctly either (probably because of the sound buffer size).

Initially, Pyxel only supported Mac and Windows because I had both environments and added Linux support thanks to operation reports of Linux users. But I'm wondering if Pyxel really can support Linux, and I'm wondering if it would be better to officially say that it will not work on Linux.

So could you give me an information if Pyxel runs on your Linux environment?
Thank you.
