Bug Reports Studio Bugs
#1

Started happening recently, but before the update that was released yesterday. Happens in any place. Resetting all settings and uninstalling all plugins did not help.

To reproduce:

  1. Go in any place (even an empty baseplate)
  2. Start a solo test
  3. Finish the test

System specs:

CPU: Intel Core i7-7700HQ @ 2.80GHz
GPU: NVIDIA GeForce GTX 1050 4 GB
RAM: Ramaxel 16 GB

Roblox Studio installed and running on an SSD.

Hello! My understanding is that you’ve yet to fully reinstall Studio. Does the issue still occur after a reinstall? If yes, can you please upload a log from C:\Users\ [youraccountname]\AppData\Local\Roblox\logs (Windows) off a session where the issue occurred? Please feel free to send the log as a DM to me if you do no wish to post it publicly. Thanks!

The issue persisted after a clean uninstall and reinstallation of Studio. Finally today, I started messing with Studio settings, and changing the graphics mode (library) under the rendering section fixed it. It was set to Direct3D11. Direct3D9 doesn’t work at all, while OpenGL produces the same result, extreme lag after playtest. Vulkan fixed that problem, but now, there is tearing. (No vertical synchronization) If I can fix that too, I will be a happy developer again. Any suggestions?

I’ve been having an absolute ton of trouble with play test…

What I am trying to test is simple and doesn’t lag at all(It’s just rotating planets what does happen is: I move 2 steps ONLY PLAY TEST screen freezes(rest of studio works) I then stop testing, can’t see the workspace because a black screen appears, this has happened time after time again in every game I go to play test, cleary a studio bug considering everything else on my PC runs fine and doesn’t lag when studio has this issue. This last time I clicked play test and studio immediately closed its-self without a single error message or “ROBLOX Studio Crashed we have to shut down” window.
