I have a fresh installation of ubuntu and I have problems trying to run Shotcut, here is my terminal output when running: sudo shotcut

My laptop is an HP pavilion dv4 with:
AMD® A6-3400m apu with radeon™ hd graphics × 4 processor and AMD® Sumo graphics.

When I launch the program it only displays a rectangle with a copy of the background.

Shotcut requires a working and compatible OpenGL. I do not know how to troubleshoot your system setup, and I do not even know if that driver is compatible and will work. You should try to confirm it is working with the glxgears command line program via apt. If it is, then report output of glxinfo | grep OpenGL.

I ran into this to after upgrading to Ubuntu 18.04. (Worked perfectly fine before that.) Same exact error message. Will investigate further and see if there’s a fix…

The same here, glxgears app is working fine, Shotcut not.

My glxinfo:

Update: AppImage is working fine, there is a problem with snap package.

Might want to update your NVIDIA driver.
For your model 397.63 is the latest.

I have a GTX 1070 and through Geforce Experience version 3.14.0.1.139 I got upgraded to version 397.64.
Windows 10.

snap apps that use OpenGL such as Shotcut are notorious for not working with the nvidia binary driver. This has been mentioned multiple times here.
