Strange Characters in Output After Update 0.3.6 in LM Studio

[jzsmoreno]

After updating LM Studio to version 0.3.6, when loading certain language models (including Qwen and others) and asking a question, the output consists of strange, nonsensical characters instead of coherent text. This issue does not occur with all models, but it affects several of them. The problem did not occur prior to the 0.3.6 update. It persists even after restarting the application and trying different inputs.

Hi @yagil, sure! Thanks for your reply. Here is the screenshot.

Experiencing the same thing with Qwen2.5-Coder-14B-Instruct-GGUF currently, little time to test others. Same kind of output.

Some work fine, like Llama-3.1-Storm-8B-GGUF.

I have the same problem on a win11 system with CPU + iGPU and it seems that the default Vulkan llama.cpp runtime causes the problem. Switching to CPU llama.cpp runtime solves the issue.
EDIT:

Posting screenshots of runtime config:

this config fails (this was the default config after 1st time installation)

this config works.

I'm having the same problem although most of the characters are all square. Uninstalling, removing everything from appdata, and removing everything from .cache/lm-studio, then reinstalling solves the issue for the first response but all subsequent responses will be the square characters again.

I wonder if this is somehow connected to many models now failing to even load since 0.3.6, or if the only commonality is the timing. Both problems began after updating.
