Can't open LotRO game window on Wine

[lotrogamer]

The launcher works correctly, but when I log in and click on a server, the game window itself won't open.
Here is what debug shows:

Solved - somehow the game switched itself from dx9 to dx10. Switching back solved the problem.

This, of course, is another issue - dx10 does not appear to work with LotRO in wine.

You could try to install dxvk [1] if your GPU supports Vulkan.
