Beorn Leonard (freen) added a comment to T74918: 3D Viewport: Jump, when mouse crosses a window corner.

Is there any progress on this? Why is it a low priority?
It's seriously irritating!!

I tried the following workaround... I increased my swapfile size from 2Gb to 8Gb. It starts to render now.
Not a bug, def.

Omar Emara (OmarSquircleArt) closed T97629: Blender is killed on rendering its 3.1 splash logo as Archived.

As you can see at the end of the dmesg report, the OOM killer killed Blender to free up some memory. So likely the scene is just too heavy for your system.

Omar Emara (OmarSquircleArt) changed the status of T90640: Mouse cursor is virtually invisible from Needs Triage to Needs Information from User.

Does this apply to the specific cursor in edit mode or to all cursors utilized in Blender?

Omar Emara (OmarSquircleArt) changed the status of T97629: Blender is killed on rendering its 3.1 splash logo from Needs Triage to Needs Information from User.

The message from ISL is probably not important. The most likely cause is that the kernel killed Blender due high resource usage, most likely due to insufficient memory.
Do you notice any unusual resource usage when this happens? Can you attach the output of dmesg after Blender is killed?

Christian Rauch (christian.rauch) added a comment to T90676: Wayland support.

However, SDL is a platform abstraction that will not be able to support platform-specific features.

SDL already has some platform-specific features, in v2.0.22 for Wayland too:

https://github.com/libsdl-org/SDL/commit/9c2f46b0d5a5dce636522904fe0afbde78016063

I'm sure, if a popular project like Blender needs more, they would be open to add them.

Omar Emara (OmarSquircleArt) added a comment to T90247: Blender often crashes with xcb-related error messages.

@Tadej Pečar (tpecar) The fix is actually provided by the libx11-git package, which is a make dependency to mesa-git, but as far as I can tell from the log, that was not installed, so maybe my assumption is wrong and this needs to be done manually.
We mainly just want to test the mesa-git when linked against libx11-git, so if you can make sure its the former uses the latter during compilation, that would be the way to do.

This is also reproducible on the CPU when setting the BVH type to BVH2. Seems like BVH2 is randomly corrupted somehow, different runs output different results. I could no reproduce in a debug build, even after multiple tries.

To try to reproduce reliably, I am simulating a key press using xdotool, but I am not able to reproduce the issue. Can you provide the UTF-8 codes for any of the characters you are typing?
Can you also open Blender with --debug-events and check to confirm that the key events corresponds to the keys you intended to enter?
