System Information
Operating system: Linux-5.6.15-arch1-1-x86_64-with-glibc2.29 64 Bits
Graphics card: Mesa Intel(R) UHD Graphics 620 (KBL GT2) Intel 4.6 (Core Profile) Mesa 20.0.7

Blender Version
Broken: version: 2.83.0, branch: makepkg (modified), commit date: 2020-06-03 14:38, hash: 211b6c29f7
Worked: 2.82a

Short description of error
Blender freezes completely when the scale gizmo is used.
The exact number of operations that can be performed before crashing seems to vary between 1 and about 10.
When frozen, the UI is unresponsive, one CPU core is pinned at 100% usage, and the system becomes quite sluggish until Blender is force-killed.
Memory usage is normal (<5% usage).
The issue doesn't seem to happen on my Nvidia card (Geforce MX150) when started with prime-run.

Exact steps for others to reproduce the error

Add a cube
Select the cube
Click on the resize gizmo
Resize on the X,Y, and Z Asis.
Result: OK. Still Working
Click on the rotation gizmo
Then click on the resize Gizmo
Result: Freeze happen, forced to restart Blender
Add a cube
Select the cube
Click on the resize Gizmo
Result: Freeze again

By deleting the .blend files in the*/tmp* folder, the user could again do more resizes, the freeze can also be triggerred with other types of actions.

The steps are not very clear.
Do we have to use the same gizmo a number of times or can it be different gizmos?

Any single gizmo or multiple gizmos can be used.

A recent problem with the undo system has been fixed.
For many it could look like random crashes.
Can you try the latest daily build and confirm that the problem still exists? https://builder.blender.org/download/

Just checked both the 2.83 and 2.90 builds. The problem still persists in both.

Hi, Have to report the same problem with someone from the french community using a Intel NUC (Intel GPU), and using Ubuntu 20.04 as OS. The issue happen more often when using the gizmo to rescale an object. The UI freeze and he can only force quit Blender.

Can this be related on "picking" on Intel? (like the pick function would go in an infinite loop because of the way the driver respond to the pick requests)
Like this change?: https:*developer.blender.org/rB3685347b4172

It happen while dragging, then freeze, then have to force Quit Blender. As mentionned, this will not reproduce every time. Need to do it a couple of times to have it reproduce..

EDIT: The user tried the last build of 2.9Alpha build (june 22) and the problem is reproductible using the scale gizmo. The issue is not present on Blender 2.82a.

Edit2(June 25) Asked the user to retest using newly released Blender 2.83.1. Waiting for the feedback.

Update: In Blender 2.83.1, the problem now only occurs with the scale gizmo and not move or rotate.

Update: (june 29)
Got new result from my french community user testing the problem with 2.83.1
User tried with 2.83.1. It still freeze.

Hardware: This user run an Intel NUC, running with and i7 processor on Ubuntu, and using the integrated GPU.

Here are the steps that were used to test:

Add a cube
Select the cube
Click on the resize gizmo
Resize on the X,Y, and Z Asis.
Result: OK. Still Working
Click on the rotation gizmo
Then click on the resize Gizmo
Result: Freeze happen, forced to restart Blender
Add a cube
Select the cube
Click on the resize Gizmo
Result: Freeze again

By deleting the .blend files in the*/tmp* folder, the user could again do more resizes, the freeze can also be triggerred with other types of actions.

@Jeroen-Bakker, do you have a setup to test the Intel(R) UHD Graphics 620 on Linux?

The driver freezes in glGetQueryObjectuiv (gpu_select_sample_query.c) when i = 3 adding any additional delay here makes it very hard to reproduce.

  for (i = 0; i < g_query_state.active_query; i++) {
    uint result = 0;
    /* We are not using GL_QUERY_RESULT_AVAILABLE and sleep to wait for results,
     * because it causes lagging on Windows/NVIDIA, see T61474. */
    glGetQueryObjectuiv(g_query_state.queries[i], GL_QUERY_RESULT, &result);

Probably introduced by d712f1f83a But due to the randomness of the issue, you should take it with a grain of salt.
