Hello,

I've a problem with my desktop computer and my devices. All work correctly on my laptop.

I think scrcpy works correctly but nothing displays any window :

scrcpy -V verbose 
scrcpy 1.24 <https://github.com/Genymobile/scrcpy>

Do you use Wayland with SDL 2.0.24? If so, see https://github.com/Genymobile/scrcpy/issues/3431

(scrcpy -v to get the version of all libraries)

This is not related to your window not opening, but: https://github.com/Genymobile/scrcpy/blob/master/FAQ.md#conflicts-between-adb-versions

[trotinet65]

I'm not use Wayland.

I think adb is running because scrcpy -r blabla.mkv works.

scrcpy -v
scrcpy 1.24 <https://github.com/Genymobile/scrcpy>

I'm surprised that it uses opengles2 rather than opengl.

Could you try with another render driver:

scrcpy --render-driver opengl

[trotinet65]

Nothing else. That's not working.

scrcpy --render-driver opengl

[rom1v]

There is probably an issue with your drivers then :/ I don't know what else could explain this.

[trotinet65]

I've tied to remove *nvidia and try "nouveau" but result is the same

[trotinet65]

I think I've found the problem. I had installed by a script. I think I've made a bad uninstall. Now, I've installed it with apt-get install but it not found it in /usr/local/bin/scrcpy. Environnement path seems to be wrong. How can clean all that please ?

[trotinet65]

Resolve after a fresh install. Thanks all

I ran into the same problem (Fedora 36, GNOME 42, NVIDIA GTX 1070 driver version 520.56.06). I managed to fix it by running scrcpy under XWayland. This can be achieved by setting the SDL_VIDEODRIVER environment variable to x11. So the new launch command becomes:

env SDL_VIDEODRIVER=x11 scrcpy <arguments here>

I had this issue on a new Ubuntu 22.04 with scrcpy

Turns out scrcpy was just running (apparently) with a size of 0x0 pixels, which made it effectively invisible. When the app was running, I clicked on it in the dock to bring to focus, then 'Alt + enter' and 'resize'. Solved my issue after a lot of headache

Weird. What are the logs in the console when you start scrcpy?

Thank you! This helps me to solve this problem :)
