Red Baron 3d with any user mods - corrupted textures after some ground action

[ArgonV]

Howdy all, running nGlide v2.10 with Red Baron 3d from Steam - and the FCJ patch... There are some bugs:

With DirectX as the backend: The mouse point graphic is corrupt when flying.
After some extended action near the ground launching many rockets and bombs, and causing fires - the terrain tiles, flames and tree graphics become corrupt.

With Vulkan as the backend: After a mission, when you exit back to the debrief screen - it appears to be under the previous action screen and you do not see the menu but only the frozen in-game screen. The menus all work if you know where the buttons are to click to exit the game, otherwise you have to exit forcefully.
The textures also get corrupted after heavy ground action.

I've read some posts using other wrappers where you can limit the amount of video memory available. Is that possible to do using nGlide?
