Parallel Projection does not work with openxr

I found that parallel projection forced through the client does not work with openxr (ticked on in device settings under the game-tab). Eurotruck simulator uses openxr and needs parallel projection on, does not show correct. I see two pictures. Elite Dangerous which also needs parallel projections forced on, uses openvr and displays correct (one picture). If there is a solution to this, please let me know.

Are you using Steam"s OpenXR or the pimax OpenXR from @mbucchia ?

If you are using Steam be sure to remove/expand steam “maximum recommended resolution” - some people already reported wrong picture if resolution too high for that “maximum…”.
Enabling parallel projections makes resolution much higher.
