The Controller Emulator always opens when I activate the Device Emulator and use some of my presets/resolutions. For some reason, this happens with my 4K size, but not the larger 6K and 8K resolutions (which can’t be set up in Roblox Studio itself, so I had to edit their registry entries)… In this video, I turn on the device emulator and the Quest 2 controller emulator pops up, even though I wouldn’t use this preset to test VR compatibility (since I have an actual Meta Quest 2). When I switch to one of the aforementioned higher resolution settings, it disappears until I return to 4K again.
Here’s a screenshot of the 4K preset, which I assume I based on the built-in 1080p preset.
There isn’t an option to disable controller emulation for a “device” (preset) and I don’t know what Roblox Studio checks for before automatically activating controller emulation. It definitely isn’t aspect ratio, as my “hi-res portrait” preset (4320x7680) also triggers it.
I don’t know when this bug “started”, since I made these presets (and discovered how to take high-resolution screenshots) last year or so, but I think this may have happened since then, so it isn’t a new bug.
