My question is, can I stop the oscillator by switching the xtal pin to ground, then turn it back on
at my opinion, answer is no. it will cause pic to reboot or malfunction or maybe freeze to some adress.
If want to add text to a video signal, why not using some BOB-3 Video-Text Overaly Module

or may want you to design your own... have a look over the net, i'm sure there's still IC that mixe 2 signal together without you have to care about synchronise them together like the old STV5730A wich seems to be obsolete or hard to find for now.
May ST9936 or ST9937 be a good start for easy solution. Seems also hard to find them too.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
