System Information
Operating system: macOS Catalina 10.15.1
Graphics card: Radeon Pro 570 4 GB

Blender Version
Blender Version 2.80

Short description of error
After hours of work with Blender the Shift key generates that the Blender will be stuck on Pan mode, all the commands then are wrong, like if the shift key remains pressed. If I close the application the problem will appears immediately after pressing the shift key, if I restart the computer i can work normally for a time until the Shift starts the error and the cycle is repeated.

Exact steps for others to reproduce the error
Very difficult because the problem occurs after working with modelling and in some moment the problem start with the Shift. Is there a workaround, Or a way to activate a debug?

If this happens, do you see the status bar changing permanently?

So you will see "Pan" there pemanently?

You can launch blender from the commandline with the --debug-events option.
(Beware! This prints out tons of entries!)

Seeing something like shift:1 in a block like this indicates blender thinks shift is pressed.

wm_event_do_handlers: Handling event
wmEvent  type:2 / MIDDLEMOUSE, val:1 / PRESS,
         shift:1, ctrl:0, alt:0, oskey:0, keymodifier:0,
         mouse:(753,363), ascii:'', utf8:'', keymap_idname:(null), pointer:0x7efcffab9388
 tablet: active: 1, pressure 0.0000, tilt: (0.3175 0.4444)

Does this happen with Factory Settings as well? [ensures no Addons are running]

I am afraid this will all not help much, I assume this might have to do with other software running? an OS thing maybe? or even hardware related?

Will put on hold though until some of this has been tried [I guess there is a very low chance of reproducing this without more information...]

Hi Phillipp thanks for your answer, I created a new 3D layout and I have two days without problems. If the problem appears again I will run the program in debug mode and i will send you the log file.

About your question. When the problem appears the status bar is fixed, i.e. the icons don't change, were freeze at "Pan" permanently. If i reproduce the error i will send you a picture of this again.

Hi Phillip, today the same problem occurs with Blender 2.81, but i record the sequence of events.
The problem started with Ctrl-R in edit mode, when I try to add new edges. One edge is no problem but when i generate multiples scrolling the third button from mouse, the problem starts.

Ok. I need to clarify that my mouse from my iMac don't works for this scroll, then I scroll using my Wacom tablet, because it works. When I hit Enter the problems start. I add two pictures, in the first one Ctrl is always 1. If i press another key, the new key and the Ctrl change to 3, then again to 1.

I hope this could help you to reproduce the error, or maybe indicate me a workaround when that happen again.
I'm not sure if the problem start with the scrolling of the mouse (3rd Button) using my Wacom, but as I remember the problem starts always when I add new edges.
The problem is not fixed closing and starting Blender, I need to restart my computer completely.

If you uninstall the wacom driver, can you still reproduce the error ? I've seen a few hick ups like that due to wacom driver bugs. In other words I do not think this is a blender bug.

Please see #72209 . I close this for now as I do not think blender can fix this issue. Check the Wacom forums for solutions. If you can reproduce the issue without the wacom driver, just reopen this ticket.
