The variant includes a long-running, but empty loop. This leads to nothing being rendered, presumably because the time taken to execute the loop causes the GPU watchdog to kick in and kill the shader. This causes the Chromebook screen to go blank, and for the Chrome Browser to lose the WebGL context: "CONTEXT_LOST_WEBGL" is reported.

Marking this as false positive, because it's OK to lose the WebGL context when a shader tries to loop indefinitely.
