You need to install the latest update to InDesign CC 2017 to 2017.1. It arrived a couple weeks ago. Should solve that problem.
There was also a patch for those still using CC 2017, but I don't know where it is.
And just in case you don't want to bother with a patch (I won't guess why you shouldn't) there is an old workaround you're talking about:
1. Turn on "Application Frame" under menu "Window".
and / or
2. Navigate to Preferences -> Advanced Type -> Show Adornment on Text Selection/Text Frame for more Type controls >> uncheck these.
It's outdated now, since there's an official patch, as Steve mentioned.
Thanks Winterm.... that's the fix I remember from the last time this was going on. I'll have to get 2017.1, though, as well.
Only workaround number 2, is a valid one.
Workaround 1 does not work for panels.
For what it worth. If I recall correctly, some users reported it worked for them - just option 1. The most used option 2.
Anyway, it's an obsolete "fix" now.
