Bug#914267: mesa: [regression] with Mesa 18.2.5-2 the charackter model in Tomb Raider is no longer rendered.

[Axel R.]

Package: mesa
Version: 18.2.5-2
Severity: normal

Dear Maintainer,

I upgraded Mesa to 18.2.5 but in Tomb Raider the main charackter model is no longer rendered. After downgrading bakc to Mesa 18.1.9 everything is working again and the model is rendered.
Here are some screens of the bug:
Multiplayer with 18.2.5: Loading Image...
Benchmark with 18.2.5: Loading Image...
Benchmark after Downgrading back to 18.1.9: Loading Image...

I can confirm this issue, on a Radeon RX 580.

Followup-For: Bug #914267

That looks like missing shaders. I hit a similar thing with mpv (just
blue window, sound but no video) after upgrading 18.2.5-1 => 18.2.5-2,
luckly showing some output that later helped with searches.

---8<---
[vo/gpu/opengl] fragment shader compile log (status=0):
[vo/gpu/opengl] 0:36(27): error: invalid input layout qualifier used
[vo/gpu/opengl]
[vo/gpu/opengl] shader link log (status=0): error: linking with uncompiled/unspecialized shader
--->8---

Bug 914303 could be the same too, garbled or single color output could
mean shaders not working because they failed to compile. Looking up
the error text, I found the culprit could be gcc, creating faulty
mesa binaries. https://bugs.freedesktop.org/show_bug.cgi?id=108646
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87859

Cheers,

Hi mesa maintainers,

after further contemplating about this, I think this bug is ugly enough
and hard to diagnose for our users, that the package should not enter
testing in this state.
I'm thus raising the severity to RC which will prevent testing migration
and also make the bug more visible to users.

Regards,
Michael
