SuperTuxKart in 18.04 : flickering shadows with intel i915 #4022

Closed Coeur-Noir closed 4 years ago

Coeur-Noir commented 5 years ago

Description

Hello,

for 2-3 weeks now I noticed glitches when I play SuperTuxKart : the shadows in most tracks are flickering. Strongly. I mean it really hurts eyes.

When I boot the same machine on ubuntu 16.04 I don’t have this flickering nightmare.

It does not seem related to kernel since if I boot my 18.04 on 4.15.0-55 problem still occurs.

I suspect some update regarding mesa, video-acceleration or xorg-*-intel but don’t really know how to narrow down the culprit…

Steps to reproduce

Well… just launch STK on Ubuntu Budgie 18.04 with intel i915 ( no other graphic controller here ).

Problem does not appear when this same machine is booted on Ubuntu Unity 16.04.

Configuration

STK release version : 1.0~ubuntu18.04.1

STK Source (PPA, distribution package, official binary, etc.) : ppa.launchpad.net/stk/dev/ubuntu

System : Ubuntu Budgie 18.04

With or without v-sync → same ( strong ) flickering effect on shadows.

So far I've seen this flickering effect in shadows on Ravenbridge Mansion, Mini Golf, Cocoa Temple, Grand Paradiso Island, Black Forest… can't say if all tracks are concerned as the problem is not « always », sometimes it stops after few minutes, sometimes it never stops.

Nice indeed !

Thanks a lot !

So who is the culprit and should I also do the same modification in Ubuntu 16.04 as a preventive action ?

later :

Daaamn… flickering is back, on « croisée campagnarde / cornfield crossing », I go on playing with other tracks… and noticed the flickering randomly on any track I think.

as suggested here https://bugs.freedesktop.org/show_bug.cgi?id=110395 I have also tried : 

MESA_GLSL_CACHE_DISABLE=1 supertuxkart

which does not change anything. After one race :

Note : my description of the problem may be misleading it seems the flickering does not affect all shadows, only trees, plants, grass. Shadows under vehicles look ok, even when shadows in landscape are flickering.

Benau commented 5 years ago

there really isn't much thing we can do, you need to pray mesa to fix their bug soon,,..

or I rewrite STK reneder engin with VK later so it may behave differently

Sorry, another question : any thoughts about https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers where there are drivers and also a supertuxkart package. Should I try these ?

Tried with padoka's ppa for newer mesa driver, but not better.

Coeur-Noir commented 4 years ago

Tried with Ubuntu 19.10 and same problem.

My computer may be old but it works so how / where to find help or workaround about this issue affecting SuperTuxKart - even if it's not your bug ?

Benau commented 4 years ago

Option 1: Use lower graphics option Option 2: Enable force legacy device = true in your config.xml

Coeur-Noir commented 4 years ago

Option 1 : you can see my graphical settings in first message. Those work vey well on that very same machine booted on Ubuntu 16.04. These settings used to work very well on 18.04 until few months ago, on that same setup.

Option 2 : I will have a look on config.xml and report, thanks.

Coeur-Noir commented 4 years ago

Setting true to enable force legacy driver leads to STK warning about missing recent openGL support and lower quality graphics overall.

So I set it back to false.

Following intuition, I changed max_fps="120" to max_fps="59" and for the moment it seems to fix the flickering shadows issue.

Let's wait…

[edit] some laps and games later, false hopes again, flickering shadows are back…

Upstream bug, in case : https://gitlab.freedesktop.org/mesa/mesa/issues/2011

Coeur-Noir commented 4 years ago

And https://gitlab.freedesktop.org/mesa/mesa/issues/1834

It seems there is a patch - but I don't know how to try it :-/

deveee commented 4 years ago

@Coeur-Noir you can download all mesa .so files from ubuntu 16.04, put it to single directory and then

export LD_LIBRARY_PATH=/path/to/mesa
export LIBGL_DRIVERS_PATH=/path/to/mesa
supertuxkart

and in theory it should work. Or maybe better try to compile that older version yourself, because it's not that hard.

Ok, so mesa patch has been provided through a ppa and should land in "regular" mesa updates, so issue is fixed, as you can see here :
