Display issues with Cadence and 4K monitors

Hello

I have recently switched to a 4K monitor and I have a lot of compatibility issues with Cadence software suite. By default, all the softwares are blurry, so I go to the properties > compatibility > scaling on high DPI settings. For all the softwares I use, the problem is solved by this action. With Cadence softwares... The result is completely random. I have no problems with Allegro 17.2 and Allegro 17.4 (the icons are a bit small, but OK)

OrCAD Capture 17.4 :
All the icons are overlapping themselves.
Text size is normal.
The software is unusable as is.

Allegro 16.6 :
All icons and texts are incredibly small... I just can't use the software as is. Strangely, the text from the menus isn't affected (text like File, Edit, View...)
By the way I don't have the tbiconsize in my preferences... Don't know why...

I tried setting the ALLEGRO_HIGH_DPI_ENABLED environment variable which didn't do anything at all. I searched everywhere in the User Pref menus, found nothing.
Does anyone found a workaround ? Is there a config I am missing ?
I find that quite astonishing that the only software that has problems using high resolution display is... a CAD software... :p

Thank you !
