Package: merkaartor
Version: 0.17~rc4-1
Severity: normal


I have found that when heavily zooming in and out while working on an area
of moderate size, Merkaartor becomes more and more sluggish, in particular 
when drwaing ways or panning.
This didn't happen with versions before 0.17, and doesn't seem to correlate
with the number of changed objects but the number of zoom operations.
"top" output doesn't look suspicious (but I have to change workspaces
to check).
Any details I can provide?

I haven't found the power lines in question, but I have been able to
reproduce the issue. I downloaded all the data in the Bale Zone and
panned around at 50m zoom, at several points rendering froze with >300%
CPU load by the merkaartor process. This was with merkaartor (0.18.1-3)
from unstable.

The good news is that it's mostly fixed in merkaartor (0.18.2-1~exp1)
from experimental. At several points there are still short freezes in
rendering, but no extreme CPU load or reasonably lengthy delays.

Kind Regards,

Bas
