DVD playback performance & debug

Hi Kodi-ers!

I recently upgraded an old xbmc installation to the latest and greatest beta release of Kodi.
Everything works fine except DVD playback, which is stuttering like if playing at 10fps.
While trying to understand if the system was overloaded, I turned on the debug logging and… that fixes the playback issue.
Obviously that’s not great because of 1) The OSD display of the cpu load & mem usage, and 2) clearly it’s a bug.
CPU load always stays at ~50% on my system so there is room to spare.

Has anyone encountered that? Is it possible to change the osd displayed content?

thanks!
