Looking at the preview window with different zoom settings changes the way it is corrupted, notice the gaps between bars is zoomed

I tried using an updated ffmpeg 4.3.1 backport, that didn't make any difference

Can you check if other software using ffmpeg plays this properly? (video editors, players)

none of those are used in the VSE, for all i know ffmpeg is delivering the frame to us like this, a developer will have to look at this, throwing random things at the wall going "could it be this?" doesn't seem like a good use of anyone's time.

Regarding endianness it seems we rely on __BIG_ENDIAN__ and __LITTLE_ENDIAN__ symbols to be defined correctly, but they are not defined in GCC. I don't build on Linux so I don't know if this has to be defined explicitly somewhere in make files. @Ray molenkamp (LazyDodo) Are you familiar with this?

Daniel Pocock (pocock) added a comment to T80912: ppc64el, Debian: video sequence editor (VSE) preview corrupt.

Another problem I sometimes see when porting code is that the size of data types is not correct for every architecture, for example, the gcc on that architecture uses 64 bits for a type but the developer has guessed it is 32 bits and hardcoded that somewhere. I feel that in this case, that is less likely than an endianess issue but can't be completely sure.

I can see that little endian is detected at the configure step and the gcc compiler is called with -DLITTLE_ENDIAN on the command line.

Daniel Pocock (pocock) added a comment to T80912: ppc64el, Debian: video sequence editor (VSE) preview corrupt.

As an endianness issue, I was concerned that some part of the code may see that it is running on ppc and wrongly assume all ppc == big endian. I've seen similar problems in other code.

Richard Antalik (ISS) changed the status of T80912: ppc64el, Debian: video sequence editor (VSE) preview corrupt from Needs Triage to Needs Information from User.

This doesn't look like GPU issue, since whole preview region is pushed to GPU as one texture.
Also I am not sure if this would be endianness issue, since x86 is also little endian.

Andrew Dionne (CepheidVariable) added a comment to T77466: Blender 2.83 crashing and lagging when rendering the viewport (cycles)..

I'm going to have to rescind my previous post actually. Today, it's gone back to crashing again. Happens within 30-60 seconds of starting blender. GPU just hangs. Also seeing a report(https://gitlab.freedesktop.org/drm/intel/-/issues/2380#note_611990) on the Intel gitlab that 2.83.5-2 is still crashing for another user, only that it's taking up to an hour to occur instead of minutes for them.

Erin M (tuxgirl) added a comment to T77466: Blender 2.83 crashing and lagging when rendering the viewport (cycles)..

It's worth noting, that somewhere between my post on August 17th, and August 21st, when the most recent Arch Linux build of Blender was packaged(At the time of this post,) a pull request was done that fixed the GPU hang on Blender's side, rather than the driver side. Version 2.83.5 still hangs the GPU, but 2.83.5-2 in Arch Linux does not.

So, it looks like our three possible choices are to use 2.82, the latest git version, or switch from the Iris driver, as Timothy suggested.

I'd still like to find the cause, though... So I'll get off my lazy posterior and get to work on poking the Linux kernel.

Emile MAEYENS (3d_2_art) added a comment to T79685: "Control key" in Linux UBUNTU does not work well in "Blender" when "Pointer Location" is activated with the program "Tweaks" of Ubuntu.

When I use Blender 2.9 and I want to use the keys [Ctrl]+[A], for instance, the key [Ctrl] does then not work properly any more in Blender, I can then no more activate it! I discovered that it was not because of a bug in Blender, but that it happened, but when I activated in the same time another program in de Ubuntu O.S., namely the software named "Tweaks", which has a function in it under the menu "Keyboard & Mouse" called "Pointer Location (Press the Ctrl key to highlight the pointer)'. Funnily , when the key [Ctrl] is activated in the software "Tweaks", then the key [Ctrl] is desactivated in "Blender".

It highlights the cursor. Rather than a ctrl press event, we get a window deactivated event, and only a release event afterwards. xev shows the same thing, so it's not Blender specific.

Does sampling work in 2.9 or is this in 2.91? Also are we able to sample outside of the blender window/env, like another program/window running in Windows, or ONLY in blender?
