Description
Hello,
I think there is a problem when using multiple page with QtWebEngine
Compile simplebrowser qt example with qt version 5.15.0 in x64, release mode
Open 6-7 tab with https://www.qt.io/ in each.
Over 2.5Gb used in total amount of GPU memory.
(depending of your GPU memory available, and if you reach the limit)
You can start getting
[9496:1392:0705/001319.853:ERROR:gl_context_wgl.cc(71)] Failed to create GL context.
Because no more memory available.
With chromium, you can open much more tabs, because the GPU memory seems to be reuse.
The example needs to add an option for better GPU memory managing?
I got the same effect in my own application.
Best regards,
Ti-R
