Flex Developed Flash Application Lags/Freezes

-

my company has developed internal flex based flash application displays grid of data , allows users scroll left right , , down view more column , row data. we've run issue our new computers when scrolling left right, application lags , tends freeze. see issue windows 10 on lenovo x1 carbon's , surface pro 4s have high screen resolution/dpi. issue not occur windows 7 or windows 10 on dell's or other machine's lower screen resolution. running windows 10 1511 , have tried multiple versions of flash player , internet explorer patches. have tried multiple display drivers no avail.

 

when testing in chrome, issue not occur.

 

can offer guidance on why application behaving poorly on high screen resolution/dpi computers?

 

thanks.

edge , "modern ie" on win8.1 , higher tend have default scale factor isn't 1.0, double-whammy of larger set of pixels need rendered, plus bunch of additional computational overhead associated handling additional scaling work.

 

that said, have surface pro 4 sitting on desk, , haven't noticed anecdotally we're having horrendous performance problems on flex apps, , fine in of our performance benchmarks.


my guess you're looking @ combination of inefficient code or other cpu-intensive loop, compounded work going on high density displays.

 

the first thing recommend taking @ application adobe scout performance profiler.  should give idea of application spending lots of time, , point towards opportunities optimization.

 

it's worth mentioning adobe donated flex apache foundation few years back, , you're using predates machines years.  inefficient in flex framework that's fixed in current version.
