Right now webrender doesn't seem to handle giant textures. These two reftests crash webrender: layout/reftests/bugs/632781-verybig.html layout/reftests/canvas/size-1.html and I'm disabling them in bug 1319188. This bug is to re-enable them.

For reference, running the 632781-verybig.html reftest produces this in the output: REFTEST TEST-LOAD | file:///home/kats/zspace/mozilla-w2/layout/reftests/bugs/632781-verybig.html | 0 / 1 (0%) thread '<unnamed>' panicked at 'assertion failed: allocation_size.width < max_texture_size()', /home/kats/zspace/mozilla-w2/gfx/webrender/src/texture_cache.rs:648 where the assertion that's failing is https://hg.mozilla.org/projects/graphics/file/73bdd29461ae/gfx/webrender/src/texture_cache.rs#l648

There are some crashtests that also run into this assertion: dom/canvas/crashtests/780392-1.html dom/canvas/crashtests/789933-1.html dom/media/test/crashtests/789075-1.html I'll be disabling these soon in order to enable the crashtests on QR builds in automation.

The WR issue is closed, I'll retest these crashtests and see what happens.

Seems to be working, except for one failure. Still, fails-if is better than skip-if. Final patch: https://treeherder.mozilla.org/#/jobs?repo=try&revision=4d704964dd009a1813e7699c980406707ff156fb
