Description of problem: With the new chromium-browser-stable-57.0.2987.133-1.mga5 I can no longer play YouTube or any other MP4/AVC video source without seeing >50% dropped frames. Downgrading to the previous stable release(55.0.2883.87-1.mga5) fixes the issue(0 dropped frames)! Below the diff in 'chrome://gpu' of both versions. Major differences in "Driver information section": All GL_* data is missing and "Reset notification strategy=0x0000" on the v57 side. ## chrome://gpu @ 57.0.2987.133-1.mga5 Graphics Feature Status Canvas: Hardware accelerated Flash: Hardware accelerated Flash Stage3D: Hardware accelerated Flash Stage3D Baseline profile: Hardware accelerated Compositing: Hardware accelerated Multiple Raster Threads: Disabled Native GpuMemoryBuffers: Software only.

Version-Release number of selected component (if applicable): chromium-browser-stable-57.0.2987.133-1.mga5 chromium-browser-57.0.2987.133-1.mga5.i586.rpm How reproducible: Play Gallium0.4/Mesa10.5.9 rendered 1080p30 MP4/AVC video. Steps to Reproduce: 1. Install/Upgrade chromium-browser-stable-57.0.2987.133-1.mga5 2. Addons installed: h264ify (to block webm/vp9) 3. Run with flags: --flag-switches-begin --ignore-gpu-blacklist --flag-switches-end 4. Play YouTube video e.g.: https://www.youtube.com/watch?v=mAPWugrTO5Q 5. Show "Stats for nerds" and observe "Dropped frames" Addendum: It may be a case where only Gallium/Mesa rendered video is affected. Or my relatively old system (Athlon Dual Core 5050e / RS780 gpu) is no longer supported? However with latest firefox (52.1.0-1.1.mga5.i586) and google-chrome for linux (google-chrome-stable-48.0.2564.116-1) I have no problems at all.

Could you try with chromium-browser-stable-58.0.3029.110-0.1.mga5 in updates_testing? I didn't change anything but the 3D acceleration is reported OK for this version. I tried to test on the same graphics hardware but it appears that mainboard is in my server where I don't usually run an X server, so I only have older and newer AMD hardware to test on. (01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS780 [Radeon HD 3200]; CPU is a dual core Athlon II X2 250e).

(01:05.0 VGA compatible controller: > Advanced Micro Devices, Inc. [AMD/ATI] RS780 [Radeon HD 3200]; CPU is a dual > core Athlon II X2 250e). I did try chromium-browser-stable-58.0.3029.110-0.1.mga5 from updates_testing today. Unfortunately, it shows exactly the same symptoms. Fact is, something changed from 55 upwards(maybe upstream!) and broke hw-accelerated video rendering with MESA/Gallium support. I think the missing GL_*DATA* is the clue. If you need me to provide anything else from my system, or do some more testing, please let me know. Here is the output of chrome://gpu. Not much difference to v57. ## chrome://gpu @ 58.0.3029.110-0.1.mga5 Graphics Feature Status Canvas: Hardware accelerated Flash: Hardware accelerated Flash Stage3D: Hardware accelerated Flash Stage3D Baseline profile: Hardware accelerated Compositing: Hardware accelerated Multiple Raster Threads: Disabled Native GpuMemoryBuffers: Software only.

I also made a color-coded diff (output of chrome://gpu) for v55 versus v57. You can see the result here:: https://ibb.co/jeeGav Besides the missing GL_* info, there are 4 more "Driver Bug Workarounds" applied, a new "Graphics Fearure" added ("WebGL2") and 2 "Disabled Extensions". Any thoughts? Thanks. Regards, B.Gombo
Please test with chromium 60 - I disabled my "build with system mesa" experiment which may have caused the problems you see.

Fixed according to previous comment. Thanks for testing!
