Sounds to me like a normal computer behaviour. CPU does use RAM to mover data in and out. Less free ram, less space to work with. Does this happen in the same conditions with an image smaller, say 250x250? It might be related to texture buffering for openGL. afaik it needs physical RAM to buffer the texture data before sending it to the videocard for rendering/processing I've had that issue when I used krita for several hours, at some point drawing would often have short freezes somewhat randomly just like in your recording. It still created the strokes as expected, "just" delayed which gets rather irritating and annoying. There was always plenty of RAM available though, and krita itself didn't seem to leak larger amounts either, but restarting Krita seemed to help. Unfortunately, I have absolutely no idea how to debubg something like that, it might be some allocator that gets into a messy internal state and needs way too long to cleanup periodically, but that's pure speculation. I've had it with various 4.2.x versions, but it's hard to say if it existed before or if it's still in 4.3/master because I just don't often that kind of patience to do that long painting session, and 4.1 (the first Krita I really used) would rarely run that long without crashing in the first place... For what it's worth, I've been painting regularly since October, on Windows, on a 32gb Thinkpad 470p and never noticed anything like this. I'm not sure how useful it is to keep this bug open? The exact same issue is happening for me as well. It seemed to have begun only recently though, starting in at least 4.3.2 and continuing in 4.4.3-beta1. It may have been happening prior to this, however, and I just didn't notice at the time. It's highly noticeable now. It's not a memory issue, as it occurs when there's well over 10 GB of memory available. It also ONLY happens in Krita. It doesn't happen in GIMP. It happens with both mouse and table pen. It also happens with a newly-opened Krita window, not just a instance that's been open for a while. Though I'm not certain, I may have begun to notice it after I upgraded my Nvidia card from a Quadro 600 to a GeForce GTX 660. The GeForce card, however, is the same card used in my previous computer, and this problem never occurred with it there, so I don't think that has anything to do with it, but I thought I'd mention it in case it was relevant. I suspect the GPU pipeline stalls -- but there isn't a whole lot we can do about that... Hi, Tiar! Could you pelase recheck this bug in Krita 5.0? I think it is the same bug I fixed in this commit: https://invent.kde.org/graphics/krita/-/commit/cbb70a7b4518f234bf905e9042faa387d8226e0f Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days.
