Same here running RUST_BACKTRACE=1 ./runservo.sh
Running ./servo executable creates windows that blinks with content for 1 sec and then fills with white color.

[YurySolovyov]

running as

./servo -G gl -b ./build/browserhtml-3e3805f69808f24d/out/index.html makes it not crash

[YurySolovyov]

Actually, it only crashes with webrender enabled

[nebulade]

Exactly same behavior on ArchLinux:

Works with -G gl but I also see content under heavy flickering, often ending up only white. Just opening a page like ars technica or wikipedia keeps the CPU fully loaded without interaction.
