Hello team,
when PDF has lots of images(ex. ppt file converted in PDF) and at that time if we use any annotation like highlight or pen, It blinks before applying change on pdf.
please suggest me if any solution on it.(I think it is rendering issue.)

opengl mode(PDFGLLayoutView) shall not blinks.
for CPU view mode, invoke VPage.vRenderSync() instead of VPage.vRenderAsync() maybe better.
