Hi all, I’ve noticed a strange behavior with Anki in the past few weeks. Every time I complete a review Anki’s RAM usage goes up by a few megabytes. This piles up over time, meaning that when I start Anki it’s RAM usage is around 500 MB, but after a couple hundred reviews the RAM usage goes up to s…

Interesting, I just did a quick test and I can also reproduce the behavior you reported not just in the add card window but in the review window as well. Moving the mouse around in the review screen increases RAM usage slightly over time just as you described. In addition, resizing the window increa…

Yea, I guess the problem occurs everywhere where Anki uses a webview to display content, e.g. the main window, deck overview, add/edit card, review, so basically most of the UI. Do you have hardware acceleration enabled? Try disabling it if that is the case.

I do have hardware acceleration enabled, but just like what happened to you I can’t disable it. If I un-check the box for hardware acceleration upon Anki restart I get this message: [image] And Anki quits out. The next time I start up Anki, Anki successfully boots up… but with hardware acceleratio…

That’s a bummer. I get the exact same error. What’s even weirder, the disabling works for me sometimes (seemingly random). Like if I uncheck and restart 10 times, I get the error (and resetting of the checkbox) 9 times, before it eventually succeeds. Although with the next restart, it will then be g…

That is so bizarre. Any hope of this issue getting fixed you think? Hopefully someone else can chime in with help too.

I am not involved in the development. In the first thread I linked @dae said that the memory issue seems like a bug in Qt, so currently not directly fixable. But if the Hardware acceleration checkbox would work again, we could alleviate the problem in the meantime.

Got it. Thanks for helping out. I hope this gets sorted out soon! In the meantime I’ll just keep restarting Anki whenever RAM usage gets high enough to cause a noticeable slowdown. At least doing that Anki will be usable until a more permanent fix is made.

It may be worth trying the ‘angle’ driver: [image] Anki Changes The moving-the-mouse-uses-RAM issue seems to exist regardless of acceleration setting, but maybe it will help with the reviewing issues you’re getting.

Thanks a ton! The problem seems completely gone for me when using the angle driver.
