qgis crashes when resetting map scale in new map view

|Operating System:||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:|
|Crashes QGIS or corrupts data:||Yes||Copied to github as #:||29473|
I work with several map views at the same time. When I try to modify the scale factor, or any of the options of the attached canvases, QGIS goes in crash. Sometimes, it signals an error, sometimes not, and it closes without warning anything.
It happens both in 3.4.5 that 3.6
It happens in 2 computers, with the same windows 10 64 bit v 1809.
Both with the OPEN_CL activated, and deactivated.
pc1: intel I7 4280, 16 Giga RAM DDR3, SSD, GTX 850ME
pc2: intel I7 6800K, 16 Giga DDR4, SSD, GTX 1060 6 giga.

I tried to debug with Qt 5.11.2 and the crash goes deep into Qt libraries.
I cannot reproduce the issue with a debug build of Qt 5.12.1, so I suspect that it's a Qt issue that was solved between the two releases.

ok, I tried now with a release build of Qt 5.12.1 and the crash is still there.
I'm not yet 100% sure it's an upstream bug and I'm sorry but I'm unable to debug it, so I'm leaving this open.
