I've tried viewing this demo in Firefox and Chrome - both freeze indefinitely. Environment: Fedora 28 Kernel 5.0.5 Mesa 18.0.5-4 xorg-x11-drv-intel-2.99.917-32.20171025.fc28.x86_64 xorg-x11-server-Xorg-1.19.6-10.fc28.x86_64
VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07)
This shader works for me on debian testing (mesa 18.3.4, linux 4.19). I also have HD 520. Can you try with latest mesa?
hi, Artem, Mark. I have the same GPU, and I checked 18.0.5, 18.3.4 (system) and built from git 19.1.0 Results: 18.0.5 - waited for about 2-3 minutes, page with shader didn't appear 18.3.4 - shader appeared after about 1 minute 19.1.0 - shader appeared after about 1 minute So I am agree with Mark, issue doesn't exist in 18.3.4+ mesa versions. (checked in FF, kernel - 4.20.16).

OK then, looks like Fedora's Mesa is outdated though in a perfect world older Mesa could receive a fix but given the fact that your resources are limited I'll just upgrade to a newer Fedora soon.

I'm just curious why it takes a whole minute for this shader to initialize? This does seem like a bug. No one will wait for a whole minute to see the results - they will consider Linux broken. Should I file a bug report about that?

I built mesa with debug flags. New results (for release versions mesa): 18.3.5 (system) - 5.6 sec 19.1.0 (git-master release) - 5.5 sec Before closing I would suggest to update mesa and re-check, whether you have the same result with me or not. In your case you can compile mesa manually, no need to make full system upgrade. btw - I am testing on fedora 29, it is shipping with 18.3.5
(In reply to Denis from comment #6) > 18.3.5 (system) - 5.6 sec > 19.1.0 (git-master release) - 5.5 sec Oh, that's just fine. This shader is quite intense - even my GTX 1060 struggles with it. Thank you for a quick response, much appreciated!
