Fedora 23, fully updated

When trying to play certain video files in VLC, I get no video and this output:
[VS] Software VDPAU backend library initialized
libva info: VA-API version 0.38.1
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib64/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_38
libva info: va_openDriver() returns 0
[00007fe38ce7a3a8] avcodec decoder: Using OpenGL/VAAPI/libswscale backend for VDPAU for hardware decoding.
[h264 @ 0x7fe38ce8ad20] hardware accelerator failed to decode picture
[h264 @ 0x7fe38cf16e60] hardware accelerator failed to decode picture
The last line repeats for as long as VLC is trying to play the file
Running "primusrun vlc" (to use nvidia card) makes the video work fine
possibly related errors in Xorg.0.log:
