Blender Version
Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-09-18 16:11, hash: 7b988188dc

Short description of error

when a modal operator has bl_options GRAB_CURSOR enabled, event.type MIDDLEMOUSE isn't raised if event.mouse_prev_x is greater than context.area.width. In other words if the mouse has wrapped around the region more than once then MIDDLEMOUSE event isnt raised.

basically, during a modal, I'm trying to get the cursor to continue wrapping around the 3d viewport after using middle mouse to rotate the 3d view.

problem 1: This bug (no middle mouse event if mouse has wrapped around)
problem 2: grab_mouse is cancelled when leaving view3d.rotate

install below addon and then press 'ctrl shift f' with an object selected, and choose solidify from the menu that pops up. move the mouse around 10 pixels to the left, press middle mouse and rotate the view, let go of middle mouse, move the cursor outside of the 3d viewport. Cursor wrapping is no longer working.

now do the same as above, but before pressing the middle mouse to rotate the view, make the cursor wrap around a few times. This time the middle mouse event isn't raised at all. But if you move the middle mouse back a few wrap arounds, then the middle mouse will be raised.

Thanks for the report. Unfortunately the scenario described is too time consuming for us to track down, we require the bug reporter to narrow down the problem.

To investigate problems with python code, a .blend file with only the necessary code in the text editor is preferable.

If the bug reporter does not provide this, the triager or the developers themselves will have to investigate and simplify the code.

And with the number of reports opened daily, this is not feasible.

ah ok, thanks. I've just pinged the hardops dev to join in the conversation, he's probably already aware of the root cause, as he's been discussing it recently.
