#1132 HiDPI broken after moving to WxWidgets 3.1.5

[Mehdi Chinoune]

HiDPI support is broken after moving to WxWidgets 3.1.5. The last nightly build that have a better support is 12312. After that the icons started to look very small and do not scale.
I have attached screenshots before and after.

OS/Distro? If on linux what is the toolkit. Please copy-paste everything from Help -> About -> Information.

I am using the nightly builds downloaded from sourceforge:

It looks like the scaling-factor was not correctly detected!

[Mehdi Chinoune]

Still present with the latest nightly build 12579

[Miguel Gimenez]

Looks like scaling factor is incorrect with wxWidgets 3.1.5 because the value returned by GetContentScaleFactor() was changed in 3.1.4

Fixed in [r12592]
