GTK3 3.24.37 reports libepoxy error (regression from 3.24.36)
Steps to reproduce
At this time I do not have a good small test case.
Current behavior
Pre-existing binaries and freshly-built binaries on a system with GTK3 3.24.37 installed will crash with a libepoxy error : "epoxy_get_proc_address: Assertion `0 && "Couldn't find current GLX or EGL context.\n"' failed". Downgrading the installed GTK3 release to 3.24.36, the binaries work again.
Expected outcome
Pre-existing code making use of GL controls in GTK3 works without failure.
Version information
Version showing problem : 3.24.37 Using Linux, and issue seen on Manjaro, EndeavourOS and others that have issued updates for GTK3 to this version.
Additional information
This issue is seen independent of hardware configuration (nVidia, AMD, intel graphics). I partitioned the failure using Manjaro daily ISOs, comparing package listings between their 20230303 (good) and 20230304 (bad) builds. Reverting the GTK3 version in 20230304 from 3.24.37 to 3.24.36 (matching the version on 20230303), tools worked again.
