Possible issue with Sodium?

[TERABITDEFIANCE]

MC 1.21, Fabric 0.16.9, Sodium 0.6.5, RC++ 3.0.3.
When changing resolution in RC++ with sodium installed, game only renders to a corner of the screen or zooms in (increasing or decreasing resolution). Tried on NVIDIA desktop system and AMD handheld system. Same effect. Mod description states compatible with Sodium.

yep. it's all sodium's fault: everything works on version 0.5.11, but as you update, starting with version 0.6.0, everything breaks down. screenshots below

ofc the old version of soduim works on the old fabric, and the new one on the new one. but sodium is to blame
