Screen orientation problem (90 deg) on pivot monitor

I have a problem with screen orientation. When I set 90 deg the picture switches beautifully and everything works great. Then after saving the settings and resetting/restarting Retroarch I got the error as in the screenshot. I’m just getting started with a pivot monitor, so I don’t know if I’m doing something wrong or if it’s a Retroarch bug. Note that this only happens on DX11. Gl and vulcan work fine.
