@arighi It's graphical demo using openGL via SDL1.2 where 1000 small discs move around and all collisions are detected, and print FPS. It uses both CPU and GPU quite heavily. (On my XPS 13 9350, intel_gpu_top reports about 55% GPU usage, and top reports 46% CPU). I was developing this for my research and this is why the hanging bug stroke me strongly. I made quick tests with the kernels that are currently on my laptop:
5.3.0-48-generic #41+lp1861395v1: 12 FPS 5.3.0-46 9 FPS + Noise (inbetween hangs, of course) 5.3.0-45 12 FPS 5.3.0-42 12 FPS 4.4.0 15 FPS (aside remark: on my antique desktop PC with Athlon 64 5600 CPU and Radeon HD6450 GPU, the performance is better: 16FPS, which is quite humiliating ;) ) ** Attachment added: "test demo" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001/+attachment/5360104/+files/test.exe -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872001 Title: 5.3.0-46-generic - i915 - frequent GPU hangs / resets rcs0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
