not sure can reproduce with same memory usage (not 10GB of free currently for the test), but open https://www.android.com/
open dev-tools (ctrl+maj+I)
move the mouse up and down in the sources elements.

Not know why you can't open DSM demo. You accept all cookies?

Hi,

I found, it's linked to GPU shared memory. I see with process explorer GPU shared memory increase from 230MB to more 3,6GB. (tested with https://ctx. olisnet .com) laptop use intel HD5500, if disable HW acceleration in chrome, I not reproduce it.

Unable to reproduce the issue on chrome version #69.0.3497.32 , by following the steps mentioned in comment#6.Hence removing Needs-Bisect label as the issue is not getting reproduced on TE end.
Could anyone from Platforms>Devtools team kindly look into the issue..

Thanks.!
