after effects issue after masking

[nanawakagimi]

Hi!

I really hope someone can help me. There is something weird happening when I try to mask a character after I'm done masking another. Like:

 - I'm done masking one clip.

 - I import another.

 - When I try to mask it, the screen goes black and keeps "flashing".

I tried everything - from clearing cache to syncing. I don't know what to do anymore.

I attached a file with recording how it looks.

I've moved this from the poorly named Community Help forum (which is the forum for issues using the forums) to the After Effects forum so that proper help can be offered.

Is there a specific address for this forum or should I just google 'after effects forum'?

This sounds like a GPU performance issue. The GPU drives AE's UI and it looks like you are having issues in this area.
Provide us with your systems specs and also ensure you have the latest driver for your GPU.

What specifics should I share exactly?

My driver is NVIDIA GeForce GTX 750 Ti if this is what you're asking about

I did. The problem didn't solve and Rotobrush still doesn't work properly, unless I missed something.
