[OpenLayers-Users] VectorLayer disappears at zoom 17 (and lesser).

[BrainDrain]

problem still exists in 2.7-rc1
vectors disappears
my solutions to avoid integer overflow in vml.js
input proj
"+proj=tmerc +lat_0=0 +lon_0=45 +k=1.000000 +x_0=0 +y_0=0 +ellps=krass
+towgs84=23.92,-141.27,-80.9,0,0,0,0 +units=mm +no_defs"), 
need this output proj:
"+proj=tmerc +lat_0=48.70975 +lon_0=44.51205 +k=1.000000 +x_0=0 +y_0=0
+ellps=krass +towgs84=23.92,-141.27,-80.9,0,0,0,0 +units=m +no_defs"
to fix problem I use output proj with offsets:
"+proj=tmerc +lat_0=48.70975 +lon_0=44.51205 +k=1.000000 +x_0=-20000
+y_0=5000000 +ellps=krass +towgs84=23.92,-141.27,-80.9,0,0,0,0 +units=m
+no_defs"
(as you can see, in my case: x-offset =-20000  y-offset=5000000)
maybe It's possible to use dd units (lonlat proj) but im my case
reprojection from mm(m) to dd produces
unacceptable features geometry
