output from /sys/class/drm/card0/error

Playing a HTML5 game exported from "RPG Maker MV" which uses a screen tint effect results in frequent GPU hangs. I don't know how they do this effect in detail, but I believe it's a WebGL application.

This is the dmesg output:

[94925.958354] [drm] GPU HANG: ecode 6:-1:0x00000000, reason: Kicking stuck semaphore on render ring, action: continue
[94925.958357] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[94925.958358] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[94925.958358] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[94925.958359] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

The entire desktop hangs when this happens for 1-3 seconds, and it happens quite frequently around every 10-20 seconds while the app is running and the effect is active. The HTML5 app otherwise displays and functions correctly.

I attached the output from /sys/class/drm/card0/error as the error told me to.
