@leocg i d/l slimjet 64 bit portable to that win 8.1 laptop and it plays both vids..

@liandri - @leocg - broke out windows 8.1 64 bit laptop and the video is broke in - opera portable 64 bit v58.0.3135.127

Also when ya X close it - on the same page the 5th video is broke..

chrome plays both..

win 10 plays both on opera and chrome..

@jamillos you're welcome..

one last thing you can try with hw acceleration on is this..

type this in opera 's address bar

opera://flags/#ignore-gpu-blacklist

and Enable - Override software rendering list

@ligardi i dunno if this will help..

try this - right-click on Opera icon and choose - Properties - click the - Compatibility tab - uncheck the - (Run this Program in compatibility mode for) checkbox and press OK..

@jamillos i think ya should try the latest opera except i would do the offline version.. Install it as a portable..

test to see if ya still have problems..

i don't think mouse is bad... but heres a couple thingys to try..

go to Opera Settings > Advanced Settings > Browser - Scroll down under system, check box (Use Hardware Acceleration when available)

If Opera is running with Hardware acceleration activated, see if disabling could help the issue to go away..

you said this - (this doesn’t happen on any other laptops with different (older) Windows)

i'm assumming your use 'n the same mouse to test the other laptops.. ummm opera does not change mouse settings.. but that win 10 update might be affecting Opera sum how..

try this in mouse settings = mouse acceleration

go to control panel - mouse - click the Pointer Options tab - uncheck box called - Enhanced pointer percision and or check the box - hit Apply - then ok

@jamillos i don't think n e one is have 'n a problem esp with the mouse like you say 'n in opera..

does those problems happen in other browsers.. and or in your windows too..

@jamillos said in Short lag after idle time:

Opera sort of hibernates after some 15 seconds, making scrolling and other things frustrating.

what other thngs.. can ya explain a bit more..

@AxelR11 if ya don't mind me ask n..
are ya use 'n - desktop - laptop
what version of windows..
what graphic card..
what version of Opera and - is it 32/64 bit..

HDMI Cable or HDMI-DVI Cable..

while in Chrome - which DisplayPort version is Selected..

ya said this - (The problem is that I can not enjoy HDR on Opera, but I can use it on Google Chrome)

so i think Hdr works in opera sorta.. but or what kind of problems ya got..

@sgunhouse i dunno may just be me.. but this is missing in opera.. this is a little bit off from subject in this thread i guess.. *sorry....

and when ya click to reply - then click upload image button. opera does not have the upload from clipboard..

Example

click 'n to reply here - right click an image - then click 'n (upload image button) to (Upload clipboard image) from an image here in forum..

Opera does not do this n e more.. the (Upload clipboard image) is missing..

@epop11rt3 i think ya said ya wanted to turn on a couple more in your screenshot of (Graphics Feature Status) so here is a couple.. if ya need more post which ones..

type this in opera 's address bar

opera://flags/#ignore-gpu-blacklist

and Enable - Override software rendering list

Enable 'n this flag will change - Hardware Protected Video Decode: Unavailable

to = Hardware accelerated..

also that same flag will change - Rasterization: Unavailable

to = Hardware accelerated..

also get chrome updated And your gaphic drivers..

@leocg this is for leocg only.. epop11rt3 Logs show same thing as this web page - scroll down over half way or so - to see the look alike log messages..

looks like an old chomium bug found here - https://bugs.chromium.org/p/chromium/issues/detail?id=764036

to epop11rt3 - seems like ya don't update n e thing often..

the audio thingy was not about if ya had issues but was for sumthing else n e ways it does not matter..

am glad ya posted screen shot.. because this is the main issue..

in your logs looks like the shader is hitting a bug in one your GPU drivers...

have you updated your amd graphic card.. looks like amd website https://www.amd.com/en/support has a couple updates for your Windows 10 - 64-Bit AMD video card.. one of them is - 1/21/2019 - the other is - 3/20/2019 -..

ok so 1 - the log also shows a bug that was in (Chrome from around 2017).. I know Opera Forum did a little work to their website lately and so when you uploaded your screen shot sumthing may have happened.. but

how old is that chrome version ya got.. lol

2 - back to the Chromium bug (Shader compile error).. your logs shows this bug was reported here - https://bugs.chromium.org/p/chromium/issues/detail?id=764036.. and also here https://github.com/Strilanc/Quirk/issues/378..

i dunno if this was fixed.. and this is way over my head..

so maybe leocg can shed sum light on this Chromium bug..

Help leocg.. please !..

Note - To epop11rt3 - answer and do what ever leocg says please..
