OSD toggling during replay does sometimes not work

[DrStrangeHH]

Tested with skin LCARS and both softhdcuvid and softhdvaapi

Replay a recording and press frequently every 1-2 seconds the OK button. OSD should appear on first press and disappear on second press. Sometimes the OSD remains visible.

I have testet this now on my NUC and can not reproduce it. Also on my CUVID installation can not reproduce it.

After an upgrade to Ubuntu 20.04 still present with VAAPI and skin LCARS
