Re: Display corruption with Kernel 5.10 and 5.12
Got now the display corruption with uImage-rb2, while streaming with VLC!

rb3 seems to be ok, have not encountered problems with it. We can move to rb4...

I did extensive testing yesterday evening and this morning with rb4 but did not succeed to create the diplay problem... (one total system freeze happened during heavy multitasking but impossible to know whether it was related to this issue). If rb3 was ok as it seemed, should rb4 include the problematic component? Or vice versa?
You have not yet revieled the exact strategy of this testing.

Git bisect is like a little wizard that walks you through recent commits, asks you if they are good or bad, and narrows down the broken commit.Roland wrote: ↑Wed Sep 29, 2021 11:32 am I did extensive testing yesterday evening and this morning with rb4 but did not succeed to create the diplay problem...

Git bisect starts with the midpoint commit. The midpoint commit is between the initial “good” commit and the initial “bad” commit.
If the midpoint commit was good, you know the commit that introduced the change is between your midpoint and the initial “bad” commit.
If the midpoint commit was bad, you know the commit that introduced the change is between your midpoint and the initial “good” commit.
After that git bisect selects a new midpoint in the area where the commit was bad. And this is repeated over and over again till the bad commit has been found.
OK, shall I execute “git bisect good” for the rb4?

No... I got now a similar system freeze that I saw already yesterday! In both cases I was downloading in a terminal window a video with Youtuble-dl, and also running with VLC a video from HD. After both freezes, only sound was still going on, but repeating itself (like an old record player stuck to repeat the same track). But this time there was also some parts of VLC window corrupted... I will try once again with the same set-up, but this smells already quite strongly 'bad'!

Please let me know if I shall execute "git bisect bad" or "git bisect good".

Re: Display corruption with Kernel 5.10 and 5.12
I got now the issue third time... This time the system did not freeze immediately, and when I moved the terminal window around on the desktop it created quite a mess on the screen.
So, "git bisect bad" for rb4!
I think I have now a 'recipe' how to recreate the issue within a half an hour. This will simplify further tests...
