If I run vlc with VLC_VERBOSE=3, I get warnings such as
[00007f4a04c13530] avcodec decoder warning: More than 11 late frames, dropping frame
[00007f4a04c13530] avcodec decoder warning: More than 11 late frames, dropping frame

[00007f4a04c13530] avcodec decoder warning: More than 11 late frames, dropping frame
when the problem occcurs. Such warnings are probably expected
since the X11 display was blocked. But it seems that something
like frame dropping is not handled correctly.
