System Information
Operating system: Linux / Manjaro
Graphics card: RTX2060

Blender Version
Broken: 3.4, 3.5
Worked: 3.3

Short description of error

blender hangs (mouse-cursor unresponsive) for 0.5 to 2 seconds, at irregular interval of every 30sec to 2min. (Not a full crash, control eventually returns)

Exact steps for others to reproduce the error

The only commonality to events is blender cursor update. Happens under all the following conditions:

mouse or pen-tablet
(cmd-line) launch normal, or launch with flag --factory-startup
just transforming ViewPort in Object-mode, or while Edit-mode on mesh or curve, or Sculpt-mode, or Weight-painting, or editing Armatures.
can be any ViewPort display-mode.
mouse can be in any part of the blender-window.
even happens with cmd-line animation player: $ blender -a
only happens in blender 3.4, 3.5. I can run 3.3 (3.3.3) right now with zero problems. Every other mouse-intensive "drawing/painting" program on my computer does not have this problem.

This started when v3.4 came out. I searched through bugs, and the only suggestion I found was to try 3.5-beta. Problem continued in 3.5-beta, and continues in Released Version of 3.5. It's like writing with a ball-point pen that only produces a line 98% of time... by the time you realize it's stopped working, your hand has moved 1-3" inches on screen, and stroke is ruined. Or like driving a car, where the steering wheel only listens to you 98% of time. :(

I did not file a bug-report before, because there is no way to describe "Steps to reproduce error". I'm filing now to provide feedback to developers, and maybe they can spot something in system-info.txt.

Thank you for blender.

That sounds kinda weird. Cursor freeze seems to be your GPU constantly running some task.

Could you try blender -d --debug-all and try to see if there are any output in the terminal during freezing and also log files?

Another way to potentially mitigate the problem is to update/downgrade your nvidia driver, try use proprietary driver.

Thanks!

I had the same thing happen when I had "Node count" add-on enabled.
May want to try disabling addons to see if it goes away.

go ahead an close this bug report. I'll keep testing, but assume it is something at my end (drivers?) for now.

To Mike: I had tried with --factory-startup and still got the problem. I thought --factory-startup disabled all the addons. ?

To YimingWu: I tried with -d --debug-all as you requested. I managed to get the problem, and then looked at the terminal debug messages. A lot of normal wm reports before, during, and after the event... but nothing that looked like blender was at fault.

re: drivers:
I've taken a deep dive into the drivers on my system. I'm using (linux) Manjaro/Arch's PRIME-RUN prefix to force my hybrid laptop (has integrated intel GPU + discrete Nvidia GPU) to run blender with only the Nvidia GPU. It confuses me exactly which drivers are in operation at which time, but I BELIEVE that it is running version 530 of Nvidia's proprietary driver.
(note that there is a LOT of chatter online about people wanting to downgrade their Nvidia driver, so apparently all is not well there.)

re: pen-tablet:
all these warn me to only have 1 driver running the tablet. I had removed previous driver & installed new when I last upgraded my pen-tablet. Somewhere along the line, Manjaro went from having the "digimend" driver being out-of-tree in the AUR (ie; not part of the normal distribution), then when I installed a proprietary driver, Manjaro changed and put the "digimend" driver (for all non-wacom pen-tablets) into the main distribution, and installed it without LOUDLY telling me during a normal system upgrade. So I had 2 drivers. (grumble). I removed one of them.

as I kept poking at drivers, my system got pretty unstable, but then yesterday, there was an unscheduled system update to "system.d" (which is pretty key to linux), and I haven't seen the hiccup since then.

I have my fingers crossed, and will keep researching. I did manage to run blender 3.5 tonight for nearly 2 hours without the hiccup/hanging issue.

Thank you all for your input and help. Thank you for blender!

I used to have my ubuntu update the kernel automatically and sometimes it broke the nvidia driver. maybe this is also that kind of weird issues.
