Hi @theerawat_4119,

Thanks for sharing the details and screenshot. Could you try updating Illustrator to the latest available update (29.7.1)? If the issue persists, try toggling GPU Performance off and on from Preferences to see if that helps. Also, let me know if this happens with all files or only certain ones for a deeper look.

Looking forward to your update.

I already updated but it's still happening. it's a bug? because I try to open on older version of Illus (v.28.0) from another PC and it's works.
Thanks for helping me.

Hello @theerawat_4119,

Thanks for confirming. Could you share a link to a sample file along with a screen recording of your workflow and the problem, so I can check this with the team?

Looking forward to hearing from you.

What blending mode are you using? Can you share the appearance and transparency panel for those objects? What is your document colour mode?
