FS#2021Cannot work with big dwg files

Openning a big file or doing any action in it, takes minutes to load.
Even dragging the scrollbar slightly left or right, takes mintues to redraw the canvas again, which makes QCAD un-usable for professional use.
Is there a way to make QCAD usable, after loading completed:
- Like suppressing edit until user says so,
- or taking snapshots of rendered canvases to another file and use it, as windows uses thumb.db ( for negative latency :P )

PS: I wish I could help a bit, but my hand are tied. I am just a java freak, I am opt to any idea of porting it to java, if she is still alive.

Huge amount of hatches.
Select all =visible, not in a block (takes some time)
Set solid (takes some time)

Lag decreases tenfold
It is still a big file
There are still hatches in blocks to render
