Minecraft freezes when minimized / ALT-TAB / Switching Window Focus

Did you encounter this issue before? Just because you're not able to trigger this issue by following the reproduction steps doesn't mean that this issue is fixed.

yes, it was really annoying and ive been checking this page for the past month for updates because i had to play on windowed as everytime i play fullscreen when i alt tab or minimize it would freeze the game just like the file resultado.mp4

i decided today to try 1.13 and i did not have that problem again. im running minecraft with a gtx 1070

Still affects 1.13

that's odd

so for me in nvidia control panel, i changed "minecraft launcher.exe" to run with "high performance nvidia processor" and "javaw.exe" to run with "integrated graphics". (a note, the javaw.exe is found in where you put your launcher and then /runtime/jre-x64\1.8.0_51

i also have all my launcher options off

does that seem to work? i guess this issue is separate from versions

Please check if that's still an issue in the latest 1.14 development snapshot.

Unsure if commenting here now is okay or not. This is the only instance of this issue that I could find. I'm currently experiencing exactly this in the 1.14 version of the game. Apologies if commenting here is not okay, this is my first time on the bugs.mojang website.

tested in 1.14 with steps i tried from my previous trial a few comments above and i could not reproduce the issue again. im not sure what else has changed on my laptop driver-wise.  i can press f11 and go to the menu and go out of the menu without it freezing. there were some people saying that discord might also be interfering in the related duplicate tickets, so maybe try to close discord first before launching the game and try fullscreening?

for troubleshooting purposes:

 - still on a gtx 1070, driver version 417.71 (ive been having issues with some of the later releases of nvidia drivers on other games so maybe try downgrading them. latest release is 430.x)

 - java 8 update 211

 - make sure you apply the nvidia control panel steps i posted above if you have an integrated card to use your GPU instead

can you post your specs as well so we can try to narrow the problem down? im sure it must be an nvidia issue as i said a long time ago because as Franco mentions when i tried to play with my integrated card back then i could go fullscreen but my fps was really bad obviously so i would prefer not playing like that

from the span of march-july 2018 i cant really think of anything i have upgraded software wise that would affect minecraft other than java and nvidia drivers. i have not upgraded any hardware components since getting this laptop in 2017 and so i dont think its related to anything physical

The first thing I tried was closing my Discord before opening the game. This fixed the issue immediately. Obviously, I'd like to have both applications open at once, though. I recently reinstalled my game (in order to see if that would fix the issue) and found that I experienced the same issue in 1.13.2 until I installed Optifine, which somehow fixed the problem. I have provided my (basic) computer specs for reference.

Processor: Intel Core i7-8550U CPU @ 1.99 GHz

RAM: 16GB

Graphics Card: NVIDIA GeForce MX150

Edit: Removed me being an idiot and forgetting the NVIDIA Control Panel existed and how to get there.

can you try turning off in game overlay for minecraft on discord? does that fix the problem? id now guess its a discord issue or an nvidia game overlay issue (might conflict with each other? i do still have nvidia game overlay on but not discord overlay)

i too use optifine but i havent tried it out for 1.14 out yet. ive been using optifine 1.13 with no issues thus far. oddly though, i did use vanilla 1.13 and 1.14 to report my comments here though

 edit: phrasing

Yep, sorry for not responding immediately when I worked it out. Completely turning off my Discord overlay fixed the problem (but turning it off specifically for Minecraft didn’t fix it for some reason). Right now it seems unclear what the problem cause is, as multiple different things can fix it. I usually use my overlay when playing Minecraft and other games so it would be preferable to have it on. Perhaps on the release of Optifine for 1.14, the problems will all go away. Thanks for your help.

Edit: Added a little more detail.

all good, you did nothing wrong. i want to solve this issue for future people as well because i know first hand it is very frustrating that you have to play either windowed or windowed fullscreen and cant play borderless/exclusive without it freezing and you having to restart the game any time you want to tab out

thats odd how if you turn it off for minecraft it still happens. we could try opening an issue on discords side to see if they can find something because im not sure if its minecraft causing an issue for discord's overlay or vice-versa. id be happy to back you up if you want to start the case on their website (im not really sure where to submit bugs there haha) but yea, we could also see what optifine 1.14 does as well before all of that.  

Problem resolved. I'm using Discord Canary (like a Beta version of Discord) so it was just a little glitch. I restarted my computer and just turning off Discord Overlay for Minecraft worked. No need to submit a report to Discord. Glad I could fix this issue. Insanely annoying.
