Civilization VI blue glitches after last update.

[nintyfan]

I updated framework and com.valvesoftware.Steam lately and Civilization VI starts displaying blue glitches.

I have this error on normal Steam installation, but this bug was fixed in Mesa and (on normal Steam installation - OpenSuSE Tumbleweed rpms) everything works perfectly, After installed flatpaked Steam everything works, but after this update blue glitches appear again.

Happen to know which Mesa release should have the fix?

It looks like mesa-17.4 , I don't know, which version introduced fix, but the game works before last Steam/Runtime update.

It has Mesa 18.0.4 currently.

[nintyfan]

So maybe it is regression. I will fill a bug report to the Mesa devs.

Is there a way to use system Mesa in freedesktop runtime (flatpak)? Some bind of files? I tried to copy files, but it complains about some private symbol in libc.

Afaik not really. You can't normally expect internals of a Flatpak to be ABI-compatible with host system

[nintyfan]

Problem solved. I do:
flatpak --user uninstall org.freedesktop.Platform.GL.default

Probably org.freedesktop.Platform.GL.default was installed automatically, so somebody must do something to solve this problem, but that's rather problem of freedesktop runtime authors.

Thanks for help.

That sounds like a fairly bad workaround. Maybe it's worth it to keep this one open for now since Summer time seems silent with regards to devs being present

Can you still get this to reproduce with the new runtime?

[nintyfan]

Meanwhile, I must remove Steam from my system. I installed it today, but it doesn't requires GL_defaults extension to freedesktop platform.
I change computer, so maybe that's the reason this extension isn't installed?

Runtime was recently update from 1.6 to 18.08, behaviour may have changed with that

If you can't repro anymore, closing as fixed. Please re-open if you notice this again

[nintyfan]

Can I test it on old computer? I think Steam allows to keep the same game on many computers, but you can get logged only from one machine at the same time.

Sure, re-open if this still happens on the old one.
