If found the way by myself, if this can help to someone, is a question of attaching the texture again and change it before the fbo generation.

Like:
```
glBindTexture(GL_TEXTURE_2D, d->fbo->texture());
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); // Linear Filtering
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); // Linear Filtering

Then it sounds like a regression… Can you check against the latest 5.7 to see if it still happens ?

"Linux itself" is a bit broad. Is it Ubuntu based ? Debian based ? Something completely custom ? Does it use a package manager ?

Hi and welcome to devnet,

You can implement a QtMultimedia backend that will use ffmpeg to read your video source or maybe the QtAV project might be of interest.

Hope it helps
