Sure, no problem. I will say that this does not appear to be an issue related to ISBoxer.
The stutter appears to be a loading time, what is being loaded is not obvious, but it is in that window that is stuttering.
1. I would start by disabling Addons to see if any of them are acting up.
2. Check the in-game configuration screen for differences in configuration between the two windows. Similarly, you can copy the Config.WTF file (found in WoW\_classic_\WTF just like the main Config.WTF file) from a known-good character (one not stuttering) over the Config.WTF file for the broken one, to ensure the same settings are being used. Each time you make a new character with ISBoxer, its per-character Config.WTF file is initially copied from the main Config.WTF file, and therefore will be synced to your latest non-multiboxing settings.
3.
