Yes, I think the compositor option in raspi-config isn't working. It's supposed to start it on boot, but I leave that setting off and just make an entry in /etc/xdg/lxsession/LXDE-pi/autostart.

Re: Qt and window opacity on Raspbian Buster (Pi4)

I have checked in raspi-config (advanced settings) that xcompmgr composition manager is enabled. Check to see if xcompmgr is actually running. In the terminal: xcompmgr If it says "Another composite manager is already running (xcompmgr)", then you know that xcompmgr is running. If it does not say t...

Re: TONS of RAM being used?

It's more likely that it's something cached in RAM. But the panel ram monitor considers the ram used by the cache as free. So does the task manager, though it has the option to toggle back and forth. With "Show memory used by cache as free" turned ON, task manager showed 1854 MB used. I'm sure it w...

TONS of RAM being used?

I use a Raspberry Pi 4 4GB as an everyday desktop computer. Occasionally, I look at the RAM monitor on the panel (taskbar) and notice that it is half-way full (~2GB). Task manager shows that indeed 1854 MB is being used, but no process shows to be over 80MB. Htop had similar results: Sorting by MEM%...

If you want the message to go away, you will have to install the correct kernel:

You can ignore the "Chromium is out of date" message. That builtin update feature of the Chromium browser is not tied to RPF/RPT APT repo updates.
