Toolbar menus distorted

In VR mode only. Toolbar itself comes fine, but all menus like VFR map or NAV log are distorted like stretching a 16:9 frame into a 4:3. Using HP Reverb G2, latest updates on MSFS, Nvidia, Windows 10. Monitor is a 32:9. No OpenXR or else in use.
Highly appreciate any ideas!!! Thank you!
