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OK then, looks like Fedora's Mesa is outdated though in a perfect world older Mesa could receive a fix but given the fact that your resources are limited I'll just upgrade to a newer Fedora soon.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'm just curious why it takes a whole minute for this shader to initialize? This does seem like a bug.

hm, agree. I re-checked timings one more time, and found out that there was my bad in calculation. 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! |
