I’m pretty much getting the same error as described here on Anki 2.1.44: Anki causing high RAM usage (v2.1.41) - #10 by owen13
Basically, over time the RAM usage keeps going up (highest I’ve seen is 6gb) and Anki gets progressively slower and slower until it takes multiple seconds to preview a card in the browser. Restarting Anki fixes it, but the cycle repeats itself.
What I’ve noticed is that hitting “Preview” in the deck browser window creates a new instance of the Qtwebengineprocess that isn’t removed when the window is closed. I’ve attached a screenshot below of what it looks like after I’ve previewed about 20 cards.
What I’ve tried to fix it:
Disabling all add-ons - same behaviour persists even with all add-ons disabled
Changing video driver to ANGLE - read that this fixed the issue for some users. I’m getting the same behaviour with ANGLE or OpenGL video driver. Unable to use Software driver since getting an error when starting Anki with that selected
Changing Anki versions - same behaviour on .48 and .31. Using 2.1.44 right now since some add-ons don’t work with .48
