System Information
Operating system: macOS-12.6-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon Pro 5500M OpenGL Engine ATI Technologies Inc. 4.1 ATI-4.8.101

Blender Version
Broken: version: 3.5.0 Alpha, branch: master, commit date: 2022-11-15 05:43, hash: 2a41cd46ba
Worked: Unknown

Short description of error
My file and/or blender can get into a state where Grease Pencil strokes will not appear until the stroke is complete and the mouse (or tablet) up event occurs. Then the stroke appears as expected. The one workaround is to turn on FILL for the stroke. Then the stroke and fill appear as expected again. Turning off fill reverts to the same issue with strokes not being visible until finished.

Notes:

I opened the same file on my Mac after closing Blender and the problem persists.
I saved the file and opened on my Windows machine (also 3.5.0) and the problem does NOT happen; strokes work normally.
I started a new file on my Mac after seeing this and the problem ALSO happens in a blank, new 2D Animation file.
This started today. Yesterday all was fine. Today I was adding layer transforms and also transforms on the GP object. Undoing these doesn't fix the issue.

Exact steps for others to reproduce the error

Open the attached Blender file in 3.5.0 Alpha version on Mac.
Switch to Draw mode and use the pencil tool to draw some strokes.
If it matches my result, no stroke will be visible until you mouse up.
Change material to include fill.
Draw with pencil again.
Now, a stroke with fill will appear WHILE you're drawing, instead of just on mouse up.

Hi, this appears to be same issue as reported in #102251 (Regression: Grease Pencil: Drawing lines appear after releasing the mouse)
So I'll merge this into existing ticket. Thanks for reporting :)
