Visit http://easyhtml5video.com/ and play video. 3.a. or visit https://www.my5.tv and play any shows to reproduce bug in flash player What is the expected behavior? Video decode should work fine on old AMD GPU when GPU blacklist are being ignored. Chrome 49 and older version did not have this problem What went wrong? Video flickering on HTML5 and Flash when hardware video decode is enabled. Not all video types are flickering so it's 50/50 Please watch my videos about video playback comparison between Chrome 49.0 and 50.0 https://www.youtube.com/watch?v=0PB2ujtMius https://www.youtube.com/watch?v=oGCxt-NzR_g Did this work before? Yes Before i updated Chrome to 50.0 Is it a problem with Flash or HTML5? Both Does this work in other browsers?

Both browser works fine, no flickering. I have downloaded drivers and BIOS from http://support.hp.com/dk-da/drivers/selfservice/hp-pavilion-g7-1100-notebook-pc-series/5082232/model/5147270?ssfFlag=true&sku=QA560EA and updated AMD drivers and BIOS to the latest version The .nfo file contains all hardware infomation about my laptop HP HP Pavilion g7-1118so notebook pc and can only be viewen on Windows computers.

Note: Hardware video decode works perfectly on Chrome 49 and older, so the problem is the Chrome itself and not my H/W. Kindly check the changes between 49 and 50.

I don't have AMD Radeon to repro. uocdung1974@gmail.com, does it this still bother you in new released Chrome dev build 53? From the screenshot you uploaded, it does look like an issue. If you disable GPU decoding, does this bug disappear?

Yes, this bug still happen in dev build v53. I tried GPU decoding and it resolve all video playback problem, but my laptop CPU is AMD with 2 cores, 3.0 GHz. Video playback is very terrible, it lags a lot and video chopping so i keep GPU deconding turned on I updated the gpu drivers from AMD website but it is not solving the problem. Chrome v49 is not obsolete yet so i can use it until this bug gets fixed Remember to ask them what CPU model, speed and fequences before telling them to try disable GPU decoding. Next time

I tested video playback on Vivaldi browser which is using Chromium and it also working fine. No video flickering problem. So i think the flickering bug came from Google Chrome software.

quocdung1974@gmail.com, can you report the display card model you are using? if this display card is put in gpu-blacklist, it probably means chrome intentionally not support GPU decoding on it. Do you see the flicking issue when you use software decoding?

My card is AMD Radeon HD 6470M. I don't see flickering issue on software decoding but the video playback is very slow due to CPU limit. In v49, it doesn't matter if my gpu was blacklisted, video playback will work perfectly like forever. v50 have ruined everything and make blacklisted gpu not support anymore. Please do not mention with my email address to get spam-bot to grab my email. please censor my email, otherwise i won't reply anymore

May i ask. Is it possible to debug and collect logs from Google Chrome client?
,

Could you check on Chrome Canary and see if it reproduces there? If it does you can get the about:gpu after you reproduce it and attach it here. It might have some additional logging info about what's going wrong.
