ffe93138751eWorked: (newest version of Blender that worked as expected)
Short description of error
blender often freezes (with the entire UI of the System), sometimes blender comes back to control, but, there are times when doesn't, the blender UI blinks to come entirely black and unresponsive.
Exact steps for others to reproduce the error
This happens when I was using a graphic tablet to sculpt something.
Just opened blender and started to sculpt, eventually the situation occur.
Don't have hardware to check, Can you check if this happens with alpha build from https://builder.blender.org/download/daily/?
Not sure what this might be... but could you check if you have enabled triple buffer on your iGPU? (Or try those options listed in there too).
I have hangs sometimes with UHD620s too, but it doesn't flicker on my side.
Does this happen without you connecting a tablet?
Does this happen with X11?
Also please share system info file (Help > Save System Info). Thanks!
I've tried without the tablet and everything goes pretty good.
This is happening with Wayland.
Update: Without the tablet blender have some crazy behavior, the UI Still responsive but the viewport gets corrupted.
Could be Wayland issue, added tag
It could be related to compatibility issues with the Linux operating system or the graphics card driver. It's also possible that there is a conflict with the graphic tablet driver.
I would suggest:
Please note that these are general troubleshooting steps and may not directly address the specific issue you are experiencing.
