Hi, In the time since my last reply, I have reported this bug upstream to mesa[1], where it was quickly found to be a deadlock in the particular graphics library framework used in RuneLite, namely LWGJL, with certain JDKs.[2] They have landed a change in their latest version which I'm happy to report fixes the deadlocks I was experiencing. Just wanted to bring that info back here to close the loop on this.
