Essentially, Dialog/DialogChoices and chat do not scale appropriately to screen resolution. This results in mobile devices and devices with smaller screens to experience odd clipping/cutting off of text.
Example of dialog cutting off completely

My Roblox Studio window size - all of it is there!
Example of chat overlapping/scaling poorly
Samsung Galaxy S8+ (courtesy of AutumnFletcher) - good golly, too big!
My Roblox Studio window size - inconsistent positioning!
Xbox One Emulation - too small, but good positioning!
In Conclusion
- Make Dialog/DialogChoices/Chat more consistent in their positioning/scaling despite different resolutions
- Create a system that allows Dialog/DialogChoices/Chat to overflow instead of cutting off based off of resolution
- HOWEVER… Dialog/DialogChoices/Chat cutting off on mobile is the bigger issue of the two
Not sure if this is a bug or a feature request. I searched for this all over the DevForum and could not find any pre-existing posts/reports about this.
