Evince's slow to select text on PDF/A - 2b format pdf type

[Abnilson Rafael]

I'm using Ubuntu 20.10, since then I noticed that in pdf document with format PDF/A - 2b, text selection is very slow.

What you expected to happen

It should've been normal to select text like any other document and no slowness. I've used Ubuntu 20.04 too, also the same thing there.

What happened instead

It's slow to select text inside the doc.
