Emulator

Yeah, not sure. I was seeing the vertex shader compile error consistently last night on 4.0-7207. In that case portions of the terrain that should have water rendered on them were just holes to the background.

That's was different than the report on the wiki against 4.0-7143, which seemed to render the water, but as static rather than waves.

I'll try to do some more testing against different releases later today.

I can confirm that...

4.0-6818: Renders water appropriately
4.0-7207: "PixelShader generator - buffer too small, canary has been eaten!" water renders as holes.
4.0-7325: "PixelShader generator - buffer too small, canary has been eaten!" water renders as holes.
5.0-rc-15: Renders water appropriately

So it seems some recent update had broken things, Needs some further testing to work out what.

4.0-7005: Renders water appropriately
4.0-7072: Renders water appropriately
4.0-7976: Renders water appropriately
4.0-7078: "PixelShader generator - buffer too small, canary has been eaten!" water renders as holes.
4.0-7099: "PixelShader generator - buffer too small, canary has been eaten!" water renders as holes.
4.0-7143: "PixelShader generator - buffer too small, canary has been eaten!" water renders as holes.

So it seems to have been caused by "Work around PowerVR's shader compiler. #2759"
