Similar issue with nvidia driver 440.82. However, on my end, the issue appears when vlc is open and reads from an external mounted drive : suspending the computer then waking up, the drive is not mounted anymore this is when the /var/log/syslog is written gigs of those same lines in just minutes.

Start a video playing, for example in vlc. 'avcodec decoder: Using NVIDIA VDPAU Driver Shared Library 418.56 Fri Mar 15 12:31:51 CDT 2019 for hardware decoding' 2. Optionally pause it. 3. Switch to another user. The original user's ~/.xsession-errors will rapidly fill up with errors along the lines of "vdpau_chroma filter error". At the same time, errors are put in /var/log/syslog as well: [00007f9d604810a0] vdpau_chroma filter error: video mixer features failure: An invalid handle value was provided. [00007f9d604810a0] vdpau_chroma filter error: video mixer attributes failure: An invalid handle value was provided. [00007f9d604810a0] vdpau_chroma filter error: video mixer rendering failure: An invalid handle value was provided. (repeat ad nauseum) At least one of the two will rapidly fill up its partition and problems will arise. With AMD video hardware and driver, the video continues playing - you can hear the sound despite being in the other user.
