Bug ID: 100697 Summary: [radeonsi,WebGL] blinking random patches instead of blinking squares Product: Mesa Version: git Hardware: Other URL: https://robertsspaceindustries.com/starmap OS: All Status: NEW Severity: minor Priority: low Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: kai@dev.carbon-project.org QA Contact: dri-devel@lists.freedesktop.org
Created attachment 130867 --> https://bugs.freedesktop.org/attachment.cgi?id=130867&action=edit Random blinking spots instead of squares
When viewing https://robertsspaceindustries.com/starmap you can see random blinking patches (see attached screenshot) instead of full screen of blinking squares in the background during the loading screens. The first few seconds of https://www.youtube.com/watch?v=Xn3MeDnryt8 show how the background should look. Please note, that the actual star map works fine AFAICT (thus the reduced severity and priority). This is with the OpenGL stack detailed below and Firefox 52.0.2. Also this doesn't seem to be a duplicate of bug 100036 as that star map seems to render correctly for me with the same setup.
The full stack (Debian testing as a base) is: GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1) Mesa: Git:master/566f2ed571 libdrm: Git:master/c9c77c3717 (tag libdrm-2.4.79) LLVM: SVN:trunk/r299977 (5.0 devel) X.Org: 2:1.19.2-1 Linux: 4.10.9 Firmware (firmware-amd-graphics): 20161130-2 libclc: 0.2.0+git20170330-1 (rebuilt for LLVM 5.0) DDX (xserver-xorg-video-amdgpu): 1.2.0-1+b1
Let me know if you need anything else.

--- Comment #1 from network723@rkmail.ru --- While I'm not a dev, but this is very similar to what I see in Xonotic, due to llvm regression, see this bug: https://bugs.freedesktop.org/show_bug.cgi?id=100681
If you can, try building mesa with earlier llvm revision, I myself use 299800 for now.

Thanks for the pointer but I've seen this issue for quite some time with different versions of Mesa and LLVM. Therefore I do not believe this to be related. I just never got around to report the bug since the main part of the map is rendering fine and the menus are working as well. It's really just the background here.

--- Comment #3 from Timothy Arceri t_arceri@yahoo.com.au --- It seems to render incorrectly in Firefox, but renders correctly in Chrome.
The Firefox console has a number of GL_ARB_gpu_shader5 warnings like:
0:2(12): warning: extension `GL_ARB_gpu_shader5' unsupported in fragment shader
For reference it runs fine in both on i965.

I meant to add that while it renders correctly the performance is really bad in chrome.

What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |FIXED Status|NEW |RESOLVED
--- Comment #5 from Kai kai@dev.carbon-project.org --- Ok, this is fixed now with latest Mesa and LLVM development builds. I'm seeing the squares correctly rendered before Firefox 61 crashes. But since all WebGL-using sites are crashing now (eg. Google Maps), this is very likely something different.
Chromium 68 doesn't crash but still renders incorrectly for me.
