artifacting with Intel A770 solitare 3.16.1+

[zlice]

Is there an existing issue for this?

• I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• The issue occurs on upstream gamescope without any modifications

Current Behavior

https://github.com/void-linux/void-packages/blob/bf7deb57efdb3ec65b02037f928727d6b1c1ea57/srcpkgs/gamescope/template

void-linux/void-packages#54145

After upgrading to 3.16.x solitare is full of artifacts and unplayable with gamescope

Steps To Reproduce

gamescope -W 1920 -H 1440 -- wine sol.exe

Does this happen with other X11 compositors as well? Also, does it happen if you run the game with proton rather than wine?

FWIW I tried to reproduce this on plasma x11 with an Arc 140 iGPU and was not able to observe any artifacts, but I only tried running the game through proton as I don't have wine installed at the moment.

[zlice]

no, haven't touched proton since it's just a small exe and not on steam

running with picom doesn't help.

$ md5sum sol.exe
373e7a863a1a345c60edb9e20ec32311  sol.exe

$ ls -al sol.exe
-rw-rw-r-- 1 zlice zlice 56832 Feb 28  2006 sol.exe

the main error seems to be related to mmap in wlroots dma

(note: vulkan in 3.16.x seems to be init'ed after 'backend' here, in 3.14.24 it seems to be before)

struct wlr_linux_dmabuf_feedback_v1_table_entry *table = mmap(NULL, table_size, PROT_READ | PROT_WRITE, MAP_SHARED, rw_fd, 0);

although the only difference in that file for wlroots between the hash used for 3.14 and 3.16 seems to be
