I know, it looks so easy but it needs a very good knowledge of what is
going on inside.

We are a FreeBSD-only shop.

No, you have to open only one document in one windows. On a machine
with only 4GB or RAM, it happens around 10 windows with 10 documents.
The documents are small. Not more than 4KB, plain text, no

Do nothing but continue to open new windows and then open a single
document in them. I change also workspace between.

It just happens when the next window is opened. The text never appears
and the text in most other windows disappears. The windows with text
still visible in them are fully usable. I did not notice any limitations
in them.

When I tried the same thing on a machine with 8GB RAM, nothing
happened. It might will happen too when much more windows are opened.

Most important, on the machine with only 4GB, I can reproduce it 100%.
