#3442 [Engine] Full context window even in new chats

说明

Hi guys, I'm running the latest AppImage and it worked really well earlier today.
But now everytime I try prompting something I get the message:
_The conversation no longer fits the model's context window. 400: {"type":"invalid_request_error","message":"request exceeds the context window: prompt (252865 tokens) leaves no room to answer in the context (65536); requests are never truncated"}
_
This problem stays no matter what I do, even in new chats, when I delete old chats or switch models.
Is there anything I can do? Or is this a bug?

Problem: <exceeded context window>
Environment: <Strata 0.2.1, CachyOS, GPU RX 9070 XT 12GB/VRAM 48GB, Qwen3.8-Flash-Next IQ2_XS and IQ3_XXS, relevant settings>
Reproduce: <exact command or short sequence>
Expected: <documented or intended behavior>
Actual: <The conversation no longer fits the model's context window. 400: {"type":"invalid_request_error","message":"request exceeds the context window: prompt (252865 tokens) leaves no room to answer in the context (65536); requests are never truncated"}>
