Symptoms

Using OpenGL, the game runs, but high resolutions (2048x1536) will cause my mouse movements to spin rapidly by itself. It seems the game does not go fullscreen, as it has a border. High resolutions also crop the mouse cursor to a smaller dimension, making it impossible to click any buttons on the outer edges of the screen. This happens with both DXVK and WineD3D.

D3D LOG:

Using Direct3D causes a black screen, whether or not DXVK or WineD3D is used.

Same behavior as Serious Sam Classic: The First Encounter.

Begin with the attached OpenGL, Direct3D, and WineD3D logs, then compare the behavior with issue #3670. Reproduce it on Proton 5.0-5 with the reported GTX 760, driver, kernel, and high resolutions; done means isolating the affected compatibility area and documenting a confirmed result.
