<pre>@Deve -
<span class="quote">>I can "fix" this by changing order of the "layer" and "wind_direction" uniform variables. Maybe it's just a case.</span >
Does it fix bisected by you commit (from Danylo)?
I made bisection one more time (and now I think that it was the most correct),
but I did what you suggested (first line in shader is "wind_dircection", second
- "layer".
As I wrote before, this issue is completely random. It can be reproduced, like,
1/5, or even 1/10 launches. Sometimes - 1 time from 2 launches.
So, 17.3.6 was stable (I did about 50 launches or even more), and 18.3.4 - with
an issue. Also issue existed in 19.0.0-rc7 (simply I had them compiled).
And result of bisection also lead me to Danylo's commit.
<span class="quote">>you may want MESA_EXTENSION_OVERRIDE="-GL_ARB_buffer_storage" apitrace trace bin/supertuxkart</span >
thanks a lot! It helped and I made an apitrace.
I will discuss my results with Danylo when he will be available.
<span class="quote">>This is on my Intel skylake system (HD520).</span >
Very interesting. I made an apitrace, and ran it on SKL (fedora 29) about 10
times. Didn't see flickerings.
Also I checked app (and apitrace) on my KBL - with 19.0 mesa version - also
nothing.
Could you please check apitrace I did?
