Problem: Audio out of sync with sllde in FireFox (65.0.1 64 bit) but fine in Opera, Chrome and IE11
ActivePresenter Version: 7.5.5

Notes: I have only noticed this problem recently, don’t know if it is due to an update in FireFox or ActivePresenter.
Update: User uses 4K screen which may slow down the computer and out of sync occurs
Maybe your content has something special since we couldn’t reproduce in our tests.
Can you please share the project and its external data folder (YOUR_PROJECT_FILE_files) if any so we can check. You can upload them somewhere if these are large then send the link to firstname.lastname@example.org
This isssue was due to the integrated graphics being put under too much load on a 4K screen, forcing the browser to use the dedicated GPU solved the problem.
