Dear Helder,
I am using IDL (8.5.1) and Win10 since March 2017 only. So I have experience of the problem with only 1703 and 1709 versions of Win10 vs. IDL 8.5. Not much !
I cannot imagine that your laptop and desktop machines can work differently in this matter. The no repeatability that you observe is also strange. Do you know whether the versions/builds of Win10 running on the two machines were different ?
Cheers,
Alx.
