[BUG] Browser UI crashes trying to load large lists of variables

[stuartpinfold]

Is this a bug in companion itself or a module?

• I believe this to be a bug in companion

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

In v3.4.0, when trying to load either the list of variables from the Variables tab then selecting a connection, or when using the drop down list while setting a command, the browser UI crashes resulting in the browser "Wait/Exit Page" dialogue appearing. This only happens when the list of available variables is particularly large, however a single connection to vMix (a few thousand variables in a large show file). I have tried a number of times to "Wait" but the list never seems to load.

In previous versions, the browser hung for a few seconds when loading these lists, but it always appeared within about 10 seconds and no further intervention.

Perhaps a solution for the drop downs might be to only display a filter list once two or three characters have been entered, rather than trying to display the whole list upon first click.

As you're using vMix, have you correctly configured its Companion module? By default, each input has variables to reference it by Name, Number, and GUID, but it's entirely possible for you to disable it showing the types you're not using. For example if you're only using input variables by Name, you can disable Number and GUID and it'll not include them in the list of variables or variable auto-complete. This lets you reduce the number of variables shown by a SIGNIFICANT amount.

Ah, I wasn't aware of this, will check it out. Regardless, the previous versions loaded the whole list, but the latest version doesn't.
