I am on Ubuntu 24.04.3 and have just seen a very odd problem. I ran an emulator build that completed successfully with release 2025070700 and then ran "emulator" and it died with a MESA dri3_alloc_render_buffer error and seg fault. I went back to a previous version of 2025030200, where the emulator has run perfectly before, and re-ran the build, and got the same error. Here is the output of the attempt on 2025070700 to run the emulator:
