QtWebEngine with consumes more than 50% CPU with LinuxFB as well as EGLFS
-
We are using Qt 5.6.3 with QtWebEngine on Sitara AM437x hardware. We are able to run the application and able to display HTML pages with LinuxFB platform but not with EGLFS platform. With this we are seeing CPU load more then 50% when we scroll through webpages.
To check with newer Qt version, we built Qt 5.15 with QtWebEngine. Now we are able to run the same application on EGLFS platform. Still we are seeing CPU load more then 50% when we scroll through webpage.
We have enabled TI SGX GPU in both cases.
Need support in reducing CPU load. -
@NPrakash
setting the following env var should reduce the CPU load for painting a bit (default: threaded):QSG_RENDER_LOOP=basic
dont know if it helps in your case, but you can also try:
QTWEBENGINE_CHROMIUM_FLAGS="--disable-viz-display-compositor"
