FS#2063 - Bad performance while zooming inside layout block with hatches

Zooming in and out is lagging to the point of unusable. This is happening in a layout block with the cursor pointing inside geometry with hatches. When the cursor is pointing outside the geometry zooming works as expected.
The attached file has a very simplified testcase that shows this problem almost in the same way as a more complex drawing with multiple layers and hatches.

edit: I also attached the more complex drawing because it is a bit unclear to me where the lagging stops. Outside the viewport or outside the paper.

I just noticed the selection box has the same problem!

I found out that locking the layer where the viewport is in will make it perform much better.

Also related to cloning load of hatches.
Gravel, Gravel1 is the culprit here
