Hello,
So I just fresh installed version 16.3.5 Full, and whenever I opened the MPC-HC these menus shows up :

and as far as I know, I never checked the automatic settings :

this never happened before on previous version, and I find it quite bothering
I did some google and take a quick look at this forum and haven't found any similar problem yet
is there any way I can disable this ?

Thanks

Do you have Slack installed?

That is a known cause to unhide those subtitle Windows. I don't know why it messes with other active applications. I suggest contacting Slack support about it.

yes, I used slack regularly for work
and yeah it doesn't happen again after I closed slack
very weird interaction, never thought slack would be the cause lol
thanks for the info, admin

Yes, it is a weird problem.

If you are able to report this issue to Slack, then please do, so that they can fix it.
