possible compositor issues with latest brewmaster and Intel Graphics (Coffee Lake) #676

Open oliverbr opened 5 years ago

Your system information

Please describe your issue in as much detail as possible:

After updating to the latest version, XCOM 1 and Rogue Legacy no longer appear in the foreground and are instead executed "behind" SteamOS Big Picture. Sound is played and the games are controllable. The cursor is changed to the XCOM-specific cursor when the game starts.

When opening the SteamOS overlay, the same behavior can be observed.

The error is present in a clean install and is not remediated by installing the missing i915 firmware files from the Linux Kernel repository.

Steps for reproducing this issue:

Update from previous SteamOS stable release to 2.189

The only interesting log data I could find after looking around in the various log locations is the steam user's .xsession-errors file, which is available at http://sprunge.us/gWkckx The SteamOS logs as described by the wiki do not seem relevant, although I can add them, if necessary.

If there's anything more I can add, please let me know.

There is a fork of steamcompmgr that is supposed to fix this behavior, you can use it for testing, see if it solves the issue. https://github.com/alkazar/steamos-compositor

Possibly related to #612.

Thanks for pointing me towards the compositor fork! I cloned the current master of the repository and installed the replacement compositor via the bundled script.

This did indeed solve part of the issue, since the overlay is visible again - I can now exit said games without having to blindly navigate the overlay (or, more often than not, reboot ;) )

However, the issues with the games not displaying remains. Rouge Legacy now blanks the screen but does not do much else; XCOM gives me the selection between using the Add-on Enemy Within or not, but does not render anything beyond that. This initial section is not rendered in the game's engine, which is probably the reason it can be shown. I was able to get past this screen before using the modified compositor, though.

I will try to fiddle around with some things I am comfortable with modifying. If there are any more hints towards debugging this behaviour, I'm all ears!

I am the developer on the compositor fork. I just tested Rogue Legacy (limited internet so can't download XCOM) and it worked fine for me on both the original compositor and my fork. I am also using intel graphics but am using the compositor on Arch Linux, not SteamOS. The original compositor has not been updated since August 2018. Perhaps the issue is not compositor related?

Do other games work? Are there any other games that have issues?

I'm no expert here, but that would probably mean that you have a different Mesa version and Kernel configuration differences. Attempting to switch to something non-SteamOS is something I will try soon.

The original compositor has not been updated since August 2018. Perhaps the issue is not compositor related?

It does seem more likely now, even if installing your fork did at least make the overlay visible again. The compositor was my first guess, given the focussing issues I described above.

Do other games work? Are there any other games that have issues?

I will try to test some other games today, but from what I've seen so far, my guess would be that they will exhibit similar behaviours.

FWIW, I tried XCOM (I don't have Rogue Legacy) on SteamOS actual, and I see no issues.

oliverbr commented 5 years ago

So I tried The Beginner's Guide and VVVVV this time around.

game vanilla compositor patched compositor
The Beginner's Guide slanted back rectangle in top left part of the screen, Steam still shown underneath black screen
VVVVV playable, but with two columns of horizontal bars drawn over the game untested
SteamOS overlay slanted back rectangle in top left corner of the screen, Steam still shown underneath shows

Since this isn't really getting me anywhere, I'll try Arch next to rule out hardware issues. (My NUC is new, but you never know...)

@oliverbr yeah, that doesn't sound normal. Something is definitely wrong. Trying a different distro seems like a good next step.
