Short description of error
Blank Grease Pencil gives dark screen

Exact steps for others to reproduce the error
The 3D viewport screen becomes dark when there is a blank Grease Pencil object.
It concerns every 3D viewport of every workspaces

To reproduce this bug, multiple ways exist :
1- Simply "add" (shift A) > "Grease Pencil" > "Blank"
2- File > New > 2D animation | Here, the default configuration will automatically put a Blank Grease Pencil object, which will automaticaly lead to the bug

Note : You can add as much Blank Object you want, the bug will remain as long as no actual drawing exists in at least one of these Grease Pencil objects

3 - If you erase everything of every Grease Pencil objects, they will all be blank. Then the bug will occur only if you

How to stop the bug

Draw in any Blank Grease Pencil object
or - Hide all the Blank Grease Pencil objects with => outliner -> "Hide in the viewport" the blank grease pencil
or - Add any Grease Pencil objects with actual drawing (such as "Stroke" or "Monkey")

/ I'm sorry I resolved the problem with uninstalling all blender (the folder in AppData)/ I'll leave the bug report if any futur person encounters it

/ To me, this bug occured in the 2.9.2/ Installing the 3.0.0 didn't solve the problem
/// Uninstalling both blender and deleting the folder in AppData (+reinstalling the latest version) resolved the problem

Hi Paulo, so you no longer can reproduce? Will close in that case.
Same issue was also reported before (turned out to be less VRAM): #94358 (Opening New 2D Animation File or New Grease Pencil Blank causes Black Window)
Thanks for the report!

Hi Patrik
I did think I solved the problem.
I didn't pay any attention to it (because I never opened a new file, always used an already created one)

However the problem came back and I don't know what to do to solve it...
So now I can reproduce it if you want me to do something.

I have a 16 Gb RAM and there seems to be 512 Mb on this laptop.
When I open blender, my software shows the VRAM goes to 165 MB to 345 MB.

Is there a way to solve this visual bug ?

Thank you

PS: I tried to do the same steps as before to solve the problem (that is to say reinstall blender), but it doesn't work ;-;

Fun fact, I just checked and the other person who has the same problem also has a Radeon Graphic (GPU) like me.
This might be the core of the problem.

I just tested on a friend's laptop and he has the same problem as me.
His laptop has an "AMD Ryzen 7 4800U with Radeon Graphics 1.80 Ghz" and my laptop has an "AMD Ryzen 5 4500U with Radeon Graphics 2.38 GHz"

The problem really seems to come from these type of GPUs.

This also reminds me of #89146 (GPencil: Viewport is Black after adding a grease pencil object)
Please double-check if the drivers are up to date.

To upgrade to the latest driver, see here for more information: https://docs.blender.org/manual/en/dev/troubleshooting/gpu/index.html

Ok, I did an update of my drivers with the "full install" to the 22.2.3 (optionnal one) and now it works !

Note :
The recommanded update (21.10.2) didn't clear the bug (just one time)

Tools :
I updated using the file I downloaded on this link :
https://www.amd.com/en/support

Conclusion :
The problem seems solved again, I'll come back if there is new things

Thank you for your support ^^
