In version 1.2.9 of the NeoForge 1.21.1 mod, there is a problem with Solas shaders (version 3.4 in use). The light sources start flashing when they are near the Create mechanisms. Especially near moving shafts.
I am creating Issues here, since the Solas version has not changed, and rolling back to Colorwheel 1.2.8 solves this problem.
I also noticed that spam errors occur in the logs:
[14Jun2026 03:04:57.443] [Render thread/ERROR] [com.mojang.blaze3d.platform.Window/]: ########## GL ERROR ##########
[14Jun2026 03:04:57.443] [Render thread/ERROR] [com.mojang.blaze3d.platform.Window/]: @ Pre render
[14Jun2026 03:04:57.443] [Render thread/ERROR] [com.mojang.blaze3d.platform.Window/]: 65539: Invalid key -1
I attach a bug video, a list of mods, and a log file.

upd.: It looks like the GL ERRORs I wrote above are unrelated to this issue. Its error from other mod... (industrial upgrade and that not all keys was binded)
