I have the same issue. I posted a thread a while ago, and also made a ticket to address the problem directly. They told me that they would forward the message to the experts and look into its fix as soon as possible.

StarCraft II: Annihilation Campaign - A 24 mission single-player campaign featuring unique heroes, custom tracks, boss battles, a varied set of mission scenarios and three intersecting storylines.
If I understand it correctly the bug is because using the latest patch.
Soo .... is there a way to revert back to older patch, one without the camera bug?
Nope, it's either using the latest patch or not being able to play online. Unlike Warcraft III and Starcraft I, there don't exist manual patches either.
If you don't open the Battle.net/Blizzard App and don't update the game, you can still use the editor with an older version. But that is depending on luck (people haven't played in a while), so even if you got lucky, you can't expect other players to not updating.
You have no choice but to wait for Blizzard to fix it unfortunately.
