[2020.08.13-2] i915 GPU hang report on 5.8.1-2-MANJARO kernel
It is my ongoing 2-month long rally of PC freezes and GPU hangs. Now it is more than 200 cases. There are no a day without GPU hangs or PC freeze.
PC freeze or GPU hang usually happens while semi-transparent, fade in/out, blur effects is/are in action. I have a feeling that fast occurred serie of GPU hangs leads PC to freeze. If only one-two GPU hang happened 'at once' than PC may freeze or may not freeze.
Posted >30 reports of a GPU hang issue. It is daily reports already. The website's captcha engine already can't recognize me human am I or a bot and shows me it's tasks to complete. Switching to 4.19 kernel lowers the frequency of PC freezes, but PS is still almost unusable. Are there any chance to start to investigate the cause of problem? Can it be planned or posted rejection to investigate?
Since prev. report #2341 (closed) got these packages updates:
grep --text -iE 'installed|upgraded|removed' '/var/log/pacman.log' | tail -n 100
...
<no any updated since the prev. ticket>Further ticket: #2343 (closed)
How the issue in this ticket happen
Minimize/maximize a window for 3-4 times. Picture freezes. Taskbar clock freezes on the 02:55:58 time moment (in HH:MM:SS format). I was able to execute (by a hot key) the script to collect error data.

Aug 13 02:56:13.905655 kernel: GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
Aug 13 02:56:13.905760 kernel: Please file a _new_ bug report at https://gitlab.freedesktop.org/drm/intel/issues/new.

Aug 13 02:56:13.905921 kernel: drm/i915 developers can then reassign to the right component if it's not a kernel issue.

Aug 13 02:56:13.906175 kernel: i915 0000:00:02.0: [drm] Resetting bcs0 for stopped heartbeat on bcs0How often GPU of PC freezes happens
Frequency of (PC freezes by unknown reason (serie of sequential GPU hangs suspected) or GPU hangs logged in systemd journal) are near highest possible. It could happen on logon screen without any user activity or during GUI session actions: on a first or 5th or 40th minute. Average is about 2-3 minutes. It is not a concrete exact action, it is general unexpected case and it did happen in (m)any types of typical user activity such as:
-) on logon screen (without any user action, even mouse touch; saw that for about 7-8 times);
-) moving desktop icons;
-) open start menu;
-) open context menu;
-) moving cursor in the text editor via keyboard navigation keys;
-) surfing in system settings window;
-) typing text in terminal emulator (GUI);
-) installing updates in GUI app or GUI terminal emulator;
-) text selection line-by-line in text editor or canceling selection in the Opera browser;
-) open or surfing in Opera web browser: list of gitlab commits viewing, filling a description of an issue ticket on this gitlab.freedesktop.org, watching youtube videos (not fullscreen and not even touch keyboard and mice at least for about last 1-2 minutes), extremely fast freeze/crash while surfing maps.google.com, maps.ya.ru;
-) LiveCD GUI sessions;
etc.
