spam and skipping/stuttering in games with "xwm: got the same buffer..." errors

[adlainewson]

Please see videos for the issue: Majesty 2: https://github.com/ValveSoftware/gamescope/assets/10458698/9942fd2a-704b-436c-864f-b01ce6b065d8

Zero Protocol (free demo): https://github.com/ValveSoftware/gamescope/assets/10458698/ef8f1ba4-df60-4079-a6a1-1c19b8b7d8e4

Problem description

• Some games appear to skip / stutter at random intervals.
• log is spammed with xwm: got the same buffer committed twice, ignoring. as the problem occurs
• Problem occurs on both my nvidia eGPU (selected with MESA_VK_DEVICE_SELECT) and igpu (intel)

Debugging info

• have tried with flags --rt, --force-composition --synchronous-x11 and various numbers for -r and --framerate-limit to no avail
• problem does not occur in embedded mode launched from tty (or without gamescope)
• I am X11 + arch + intel/nvidia (550, but problem also occurs in 555) gamescope 3.14.22

Following is an example log from gamescope -h 1440 -H 1440 -- steam then running Zero Protocol and loading into a saved game, where the problem occurs (log cut after at the relevant error spamming log)

console: gamescope version 3.14.22
No CAP_SYS_NICE, falling back to regular-priority compute and threads.
Performance will be affected.

Hmmm w/ nvidia 535 driver, I’ve also seen that message when running glxgears on gamescope …

What happens when you run gamescope -- vkcube? If that crashes/hangs, what about DISABLE_GAMESCOPE_WSI=1 gamescope -- vkcube?

Interesting; running without the flag seems normal, running with DISABLE_GAMESCOPE_WSI=1appears to replicate the stuttering, but without the xwm error messages.

[sharkautarch]

@adlainewson When running gamescope nested, I suggest you put gamescope -h 1440 -H 1440 -- %command% In the launch options, instead of running steam ontop of gamescope

[adlainewson]

thank you, sometimes running steam in gamescope gets around some errors - in this case there is no difference if gamescope runs steam or steam runs gamescope.
