Blender Version
Broken: (example: 2.80,
edbf15d3c0, master, 2018-11-28, as found on the splash screen) 2.92.0Worked: (newest version of Blender that worked as expected) 2.91.0?
When using blender 2.92.0, I have been getting crashes. It appears to be when an Automatic Save is happening and I click anywhere in the UI.
Exact steps for others to reproduce the error
This is a little difficult, I know not a good answer. It has to do with the timing of when an Automatic Save happens and at the same time a click in the UI. At first, I thought it was about changing from wireframe to solid to renedered view. I them was working in solid view and reposition the cursor and got a crash. I will attach the crash report for this one as it helped me narrow down that it was tied to the automatic save as the time stamp on the crash report and the automatic save file are the same.
Based on the default startup or an attached .blend file (as simple as possible).
It is based on default setup. No simple blend file. This is happening in all blend files that I am working on. The larger the more likely it is to happen.
The automatic save time is set to 1 minute.

@PratikPB2123 wasn't able to reproduce this on windows.
@Phred42 Could you try turning autosave off and then reproduce the issue? I would like to narrow this down further.
I have two reports for you:
1 - I changed the autosave down to 5 minutes and it occurs much less. I think once now since I reported it.
2 - I have turned autosave off and will test further. If it occurs I will report.
It is a difficult one to reproduce. I don't know if size is a factor on this. I have added a screen shot of the blender file. It has a lot of linked files (at least for me). I wish I had more concrete steps to reproduce. It is frustrating to not have enough to work from. This one looks timing related but I am not sure.
The problem is that if it is happening in a complex file, the root cause might be something else entirely. If we cannot reproduce this with the autosave in a small file, then it likely isn't the problem.

I have same issue. I sculpt some and on taping the screen blender crashed and no auto-save file were made so I lost big part of progress. Or it might be that file auto-save file was made but it do not include 30 min sculpt progress ((( Kurilenko_11908_autosave.blend Kurilenko.crash.txt
I have same tuf gaming laptop with 4800h and 1650ti gpu
@krooooglov I assume that you claimed the task accidentally since we don't even know what the bug is at the moment.
The bug is that blender crushes while auto-save

The crash happens in
DrvPresentBufferswhich reminds me of #85977 (NVidia: Random crashes in 'DrvPresentBuffers').Since in this report we also do not have consistent steps on how to reproduce the bug, I will merge the reports.
(The
AMD Ryzen 7 4800Hmust not be related to the crash).Closed as duplicate of #85977
