[paul summers <paulsum@xxxxxxxxxxx>]

this occurred in the past, but using latest nvidia drivers fixed it (i
think), but this time I  am not using Nvidia drivers... ( just the stock
drivers that are included the updated 12.0.3.

i am using a haswell g3420 Intel graphics, with vaapi normal.

this bug is not really important does not really cause problems except
for the error popup.

but was DOES  cause errors is the front restarting/crashing because you
are exiting the video/tvshow you are watching using the esc key...

dont think that this bug has to do with the playing of tv shows...
