Dear maintainer, I am affected by the same error as the opener.
If I start liferea by terminal I get following errors/messages by clicking on an message to show it in window 3: LANG=C && liferea sys:1: Warning: g_atomic_ref_count_dec: assertion 'old_value > 0' failed KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied Failed to create GBM buffer of size 469x199: Permission denied KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied Failed to create GBM buffer of size 469x199: Permission denied KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied Failed to create GBM buffer of size 469x199: Permission denied Failed to create EGL images for DMABufs with file descriptors -1, -1 and -1 sys:1: Warning: g_bytes_get_size: assertion 'bytes != NULL' failed sys:1: Warning: g_bytes_get_data: assertion 'bytes != NULL' failed sys:1: Warning: g_uri_is_valid: assertion 'uri_string != NULL' failed Maybe that help you to find the error. If it is important: I'm using an nvidia-card in the system with the proprietary driver. Kind regards Thorsten
