Proton 6.3-1 input stuttering #4734
Comments
i can confirm this happens on Risk of Rain 2 and Scrap Mechanic. |
I am not sure if this is the same issue, but after playing for a while (30 minutes to 2 hours is a good estimate for me as well), mouse input gets really poor and stuttery. I ran into the issue with both RDR2 (which I could fix by switching to a software cursor) and Amnesia: Rebirth (Didn´t have a software cursor option, so restarting was the only fix). Happening for me under 6.3-1 proton as well. |
Same issue in Natural Selection 2 here, it's like issue #3316 reappeared. Mouse input seems to drop to a ~4Hz pollrate which makes for insane amounts of stutter when looking around. |
Yes, a 4hz pollrate seems best to describe my experience as well once this bug is triggered. |
I think I am also facing this issue. |
Got this in Squad as well. Initially it does feel as if the input poll rate drops to a constant 5-10 Hz (not really 4 Hz IMHO), but I don't think I'm seeing what I'd expect in that case. I get a slideshow, but I don't remember noticing motion blur between the frames although it's enabled in-game. If it were just relatively large jumps in mouse input then wouldn't the frame postprocessing add a noticeable amount of "blur streaks"? I'm not 100% sure though. I need to run a test with in-game blur maxed out and see what happens. Maybe it's input stutter and UE4 handles long input intervals as if recovering from a network lag spike, i.e., a quick screen update with minimal postproc? |
Happened in Killing Floor 2 and Phasmophobia, probably happens on all games. It is like mouse input is refreshed every time you move 50 pixels so it moves very 'blocky' like it reposition mouse only after a specific movement threshold. |
For people sharing this experience, make a gist with your Steam: System Information so we can gather all the data. It might be combination of hardware and drivers, like a missing VK_ extension, so give all the info you can. It takes only a minute or two, but speaking from experience, it really helps in fixing bugs. |
I have experienced the bug in Halo MCC and Subnautica. The bug appears to occur randomly typically after 15 minutes - 1 hour of play. I doubt it's a system config issue, looks a lot more like a WINE bug to me. |
Here is my sys info https://gist.github.com/Zorrototo/a66b5307ae5deced2352dfa41a786846 |
I'm experiencing an input lag of my mouse after a while in Death Stranding. Game itself runs smooth (as shown with MangoHud, solid 60 FPS). It's like the mouse would snap into certain positions (similar to turning in VR with snap turning) when looking around. |
I am also experiencing mouse stutters after a while of playing on 6.3-1 rx 580 ryzen 5 1600x |
confirming the bug. It also happens when you run scripts with recent enough wine version through steam as non-steam game. short video of warhammer online run through a script inside steam client (sadly didn't have mangohud enabled) happens after 1+ hour of playing, but only when launched through steam. LD_PRELOAD="" seems to work around this nasty issue for now. from the VKx discord it looks like its already known what causes it. something to do with explorer.exe and PE builds of dlls that interact with the steamoverlay or something along those lines. |
I tried that with Amid Evil but it seemed to reintroduce this bug: #4577 Clearing the LD_PRELOAD can be a nice workaround (looking at you, Civilization) but generally speaking it's a bad idea. Perhaps somebody else can try it with another game and have more success. |
Can we please properly define which issue we try to describe here and change the title accordingly? @Eonfge Can you verify whether you reported this issue due to stuttering or input lag and change the title accordingly? |
Here is my steam info: https://gist.github.com/raQai/37a4554130250b9be9dab9e1be824e9f Stuttering also occurs in Borderlands 1 and 2 (probably also Borderlands The Pre-Sequel). |
@raQai it is neither stuttering nor input lag. It is like the mouse teleports itself after you have moved a specific threshold, like it has been said the mouse snaps in places when you move it, it doesn't follow the real mouse movement but it snaps like on a grid. |
Same here with Mordhau on Arch Linux via Proton 6.3-1 |
Confirming Quake Champions. |
Go back to Proton 5.13 |
Thanks all for reporting. We understand the problem and hope to have a fix soon. In the meantime, Proton 5.13 is unaffected, as @Zorrototo said. |
@aeikum Sounds like a plan. Let us know when you got a patch and we can run it through the gauntlet. |
Hey everyone. I've uploaded a build that will hopefully fix this on the "next" branch of the Proton 6.3 app. Please give it a try and report back if it is working correctly for you. |
@aeikum Seems to be fine for me with 6.3-2-rc1. Others will have to confirm, but input stuttering seems te be gone. |
@aeikum The problem was solved, but now in Alan Wake, when wanting to exit the game, it freezes, after a minute I have to force it to exit. |
Hello @iWeaker4you, that sounds like a note to add to the Alan Wake compatibility report since that isn't directly linked to the issue being tracked here. |
Earlier the issue appeared within 30-60minutes. Now I've played using 6.3-next for 3½hours without triggering it. Seems solved. |
Proton Experimental is Proton 6? I am having this problem on World of Warships, after 3 or 4 games, like 40min of game play, the game start to stuttering when moving the mouse, I need quit and enter the game again. |
Proton experimental is its own branch. |
Same stuttering on mouse input noticeable when looking around in game, only happens after an hour or so of play. System information

@gbschenkel No, you'll have to go to Proton 6.3, preferences and then under beta's you can select 'Next'. It also wasn't completely clear to me initially, but from Steam's point of view Proton 5.13, 6.1, and Experimental are different products. To test something related to a specific version, you'll have to use the build-in beta system. |
Thanks all for reporting and retesting. I've just pushed that build live on the Proton 6.3 app. The Experimental app should be updated later today. |
The fix is now also on the Experimental branch. |
Thanks @aeikum, how was this fixed (what commit/change)? |
Just commenting back that the fix works for ARK: Survival Evolved. Thanks @aeikum |

Compatibility Report
System Information
I confirm
Symptoms
After some play, anywhere between half an hour and two hours, I notice a significant input stuttering/choppiness. With Mango Hud, I can deduct that it's not something FPS or frametime related and I've also checked for background tasks that could potentially ruin things.
Based on feedback, it seems to be that this is a regression:
