Je voulais pas faire un edit...
Comme je suis un peu juste en "English in the text" est-ce que ça pourrait venir de là:
Known issues 0.18.4:
Windows display driver
There are issues with Radeon graphic cards. If your objects show transparency where they should not, it may be caused by the Radeon driver.
Workaround: Rollback to an earlier driver graphic card driver version.

I have a Radeon RX 460 card. It appears that I updated the driver on July 23, 2018. The updated driver was version 24.20.12019.1010 (from Radeon Driver Package 18.7.1). I rolled it back to the version that was previously installed, 21.19.407.0, and that resolved the problem. I then rolled it forward to 24.20.11016.4 (from Radeon Driver Package 18.5.1) and I still don't have the problem. Yay!
Here is another report of issues with a Radeon 5470 and a driver solving it: https://forum.freecadweb.org/viewtopic
