updated the shadertoy with a 
#define BUG 1
if that defined is commented, webgl doesn't crash.
otherwise it crash on my android one plus one.

But just that code part doesn't crash (tested here: https://www.shadertoy.com/view/4syyRW )

Can someone from test see if we have a One Plus One and see if this reproduces locally? It would be good to get a crash dump or callstack for this issue.

My guess is that we should either:
- Apply a workaround in Angle in the shader validator.
- Blacklist some (crashing) shader feature in Chrome.

Tested the issue using #65.0.3325.109 on Samsung J7; 7.0.0 and could not reproduce the issue as per the steps mentioned in original comment.

Requesting MTV team to check this issue on Android one plus one as device is available there.

Thanks!!

I can repro. Looks like the shader takes over 10 seconds to compile, in both Chrome and Firefox. Firefox just freezes until it's done, while Chrome's watchdog kills the GPU process after 10 seconds. This is working as intended, as we don't want to hang the UI for that long.

It seems like the shader ought to compile faster, but that's up to the driver. I'll report it to Qualcomm.

Would appreciate a lot if someone could edit the bug report first link on the line "we had the bug on ..." to https://sketchfab.com/models/5455e3e149484c9cbdbf3903fa0ff691

I don't believe comments can be edited here. Thanks for the report though!

Comments can't be edited, but bug descriptions can. Done.

Thanks a lot !
