Quick follow-up:

- I've tested SweetHome3D on a fresh Ubuntu 17.10 install, and it frozen when I started drawing a wall (tried twice)



- back on my main computer running arch, I've tested SH3D version from 4.6 to 5.4, here is the summary

• * 4.6: responsiveness OK, HDPi support NOK (click is shifted, icons are two small, drawing grid is too small)
  * 5.0: responsiveness OK, HDPi support NOK (same)
  * 5.1: responsiveness OK, HDPi support NOK (same)
  * 5.2: responsiveness OK, HDPi support NOK (same)
  * 5.3: responsiveness NOK (oops), HDPi support OK (yay )
  * 5.4: responsiveness NOK, HDPi support NOK (click is shifted, icons are two small, drawing grid is too small)
  * 5.5: responsiveness NOK, HDPi support NOK (same)
  * 5.5.2: responsiveness NOK, HDPi support NOK (same)

So, seems something is going on with 5.3 release. Given this release fixes the HDPi support (for me), it may be that the responsiveness issue is related.
Strangely, starting from 5.4, HDPi support is broken again (for me), but the responsiveness isn't fixed.
Sadly, from this quick investigation, I see that there is no release with both responsiveness and HDPi support for me.

Any hint out from those new elements? Anything I can test out?

Thanks
