I've seen this debug option being mentioned for people having problems using Blender on Intel Graphics but, I tried it with GZDoom and I no longer get the following problem happening anymore:

With INTEL_DEBUG=reemit set, I get non corrupted rendering:

Can anyone else with Intel Graphics older or newer than Skylake test running GZDoom with INTEL_DEBUG=reemit set and tell me if what happens in the screenshot continues to happen? This specific spot in Kinsie's test map will always expose the graphical error.
This does seem to lower performance ever so slightly however, but I'll do some more trial runs of this later tomorrow.
The description for that debug option just says: "mark all state dirty on each draw call"
