@nvmjustagirl nope

@nvmjustagirl Hi, disabling hardware acceleration fixed video playback (with cost to cpu utilization of course)

@leocg any idea if some support of GPUs was dropped since 51? nothing mentioned in release notes

@nvmjustagirl its 64bit, exactly with the same driver (WU provided ) which you mention. anyway, the videos are broken just since update to opera 51. in MS edge and firefox 59 i have no issues.

@leocg

@leocg, well tried that first but the forum says i do not have permissions to upload txt file which is log output of media-internals. Can you please be so kind what you mean by "se the proper function on that page" ?

@leocg see opera://gpu diagnostics. https://uloz.to/!xY5w2OLUDfwm/a-oxps
just to note, all videos work well in current chrome on same PC

@leocg guess it depends on gpu type somehow. on 2nd pc with very old intel HD 2000 graphics all fine, on pc with radeon 4600 series video is broken like shown, but audio works.. i was trying to adjust nearly everything within opera://flags related to gpu / rendering but no luck..... not sure if support of some features were dropped from 51.
