screenshot showing the glitches

In the Load game menu and inside the game witcher 2 glitchers a lot.

sadly I can't create an apitrace, because the game crashes with MESA_EXTENSION_OVERRIDE=-GL_ARB_buffer_storage and setting vb_dirty = 1 and cb_dirty = 1 doesn't help (in nvc0_vbo.c:nvc0_draw_vbo)

It works with intel.

All settings set to minimum.

Is this still a thing? There was an issue that was causing blurriness in Witcher2 for joi that went away with http://cgit.freedesktop.org/mesa/mesa/commit/?id=e50c01d5af305e07110cb4a38d5a655437058f04 . I somewhat assume he would have noticed such massive glitching...

the issue is still there, but I got a working workaround: go into arena, then load the game. It's fine this way.

seems like the issue gets worse the lower the core clock is, for reasons I don't understand
