Trials Evolution - Screen Covered by Giant Black/Blue Grass Sprites

[Enverex]

The game's a complete mess in stock Wine but works almost perfectly with the exception of one graphical glitch in DXVK; During a race, the screen is almost entirely occluded by giant black and blue grass sprites. Screenshot at the bottom of this report. This particular bug doesn't happen in native Wine.

Hi,

looking at the logfile, the game seems to need stream output, which is not supported yet.
In addition you are using the 396.24 driver which has some issues with tesselation which are fixed in the vulkan beta driver 396.18.11. So you may try your luck with the mentioned driver and see if your issue is fixed. If not, it might be related to the missing stream output .

Many thanks!

Thanks for providing a working trace file. Can confirm the issue on RADV, probably related to missing stream output as indicated by the log files (see #135).

Confirmed to be a stream output issue. Apparently the grass does not render at all with latest master due to a somewhat change that clears buffer contents to zero.
