Bug#1104410: gamescope crashes on launch

[Michael Young]

Package: gamescope
Version: 3.16.1-1
Severity: important
X-Debbugs-Cc: mtorpey at mtorpey-study.Home

Dear Maintainer,

Every time I try to load gamescope it crashes with an assertion failure:

gamescope: types/wlr_linux_dmabuf_v1.c:532: feedback_compile:
Assertion `table_len > 0' failed.
Aborted (core dumped)

This seems to be the same bug as reported at
<https://github.com/ValveSoftware/gamescope/issues/1218> which is
apparently fixed upstream in 3.16.3 and newer version. Possibly it's
just time to package a newer version.

Here is a full output:
