Summary0005055: Incorrect shadow mapping when using Stencil shadows + Soft shadowing
DescriptionThere seems to be an issue with shadow rendering in the engine: When enabling both Stencil Shadows and Soft Shadows, shadows get incorrectly mapped and are stretched across the screen in front of the camera. I have no issues when using Stencil Shadows without shadow softness, nor when using Map Shadows both with and without soft shadows.

I attached two screenshots from the FM Full Moon Fever: The first shows stencil shadows without softness (normal results) and the second is stencil shadows with softness (corrupt shadows).
Steps To ReproduceGo to: Settings - Video - Advanced - Experimental Features. In this menu set: Shadows Implementation = Stencil, Soft Shadows Quality > Off (Low, Medium, High, Very High). Linux users with AMD video cards using the amdgpu module and Mesa should notice the corrupt shadows.
Additional InformationI'm running TDM 2.07 x64. My operating system is Linux openSUSE Tumbleweed x64. Kernel 5.2.14. Mesa 19.1.7 (amdgpu module). My video card is an AMD Radeon XFX R9 390.

Could you please attach darkmod.cfg and condump with soft shadows enabled?
Do you have the 2.07 hotfix version? (You can run tdm_update and try again to ensure it)
Given that 2.07 is out for quite some time, did this problem come up recently? Was/is it working in 2.06 (if you played it) ?

Let's watch over this problem during 2.08 beta.
The rendering has changed a lot since 2.07, including the almost finished Core Profile.

That looks like Render Scale set to something other than 1 with Stencil Shadows. That feature works with Shadow Maps only.

Probably related: 0005068 (non-default r_fboResolution is buggy underwater).

It would be interesting to check if the problem can be reproduced with r_fboResolution + stencil shadows. Such case should either work properly or be impossible to set via menu graphical settings,

I can confirm that I see this issue with:
  r_fboResolution 2 (or 0.5)
  r_shadows 1
  r_softShadowsQuality 12
on any map.

With r_fboResolution > 1 I see some additional weird effects on skybox and torch flames.
These effects do NOT go away if I switch to shadow maps.

Interesting. Indeed this sounds like it might be related to 0005068 which was also caused by having r_fboResolution set to a value above 1. I changed that in my config so I should no longer be getting this either.

Here is the config file to be sure it could be reproduced.

The problem with r_fboResolution > 1 are still present:
  when I look at skybox, it becomes brighter every frame (getting VERY bright)
  when I look at flame, haze effect is broken
With r_fboResolution < 1 it does not look bad, but I guess it still does not work as intended.

Should I create anothenr issue for it?

Yeah, I think a separate issue would be great, because I can't repeat it yet
