ever since i upgraded to windows 10 i get this issue where if i have Fixed Window set if i alt tabed too much no matter how much time passed between the previous alt tab, it will lock up the computer, graphically, i can still hear sounds and music. i even tried a clean windows install, and it even happens on multiple computers i’ve tested it on
I’m also having this issue on multiple computers (both at home and my work computer), with different CPU/GPUs and the latest drivers and Win10 updates. My displays completely locks up, while I can still hear sounds from Mumble and other apps. I have to cycle power on the PC to get it running again.
I’m glad to see its acknowledged, I came here today to post this issue. However I tried the fixes and there is no change on my computer.
I run two accounts usually preferably in fixed window. I’ve taken a long break but upon coming back I’m noticing an alt tabbing problem which I’ve never had before for years. The lag can totally lock the system up for 5 seconds or so, or it can just stutter and continue along. It also blocks inputs entirely and loses them … sometimes.
Another strange symptom is it varies from alt-tab to alt-tab and isn’t consistent at all. And it seems like everything I do that could affect video performance seems to affect this issue, but never resolve it. For example if I switch to Fullscreen then the problem seems to go away completely for a little while (hours or minutes, there is no telling). Then it comes back in full force until I switch back to Fixed Window. Out of the game I can shut down Geforce Experience since I have shadowplay on and there is an overlay associated with that and the problem seems to go away. For a minute then it comes back. I haven’t messed with Window mode a lot cause I dont want to use it even if it was a workaround because of what it does to all the dialog boxes.
After following the workarounds that I could in that link I cleared all my cache and rebooted. Then I uninstalled and reinstalled. It actually seems worse now but that is probably a coincidence.
It only seems to happen when two clients or more are running. One works great in any mode I’ve tried.
Windows 10 Pro 64bit all updates
EVGA 1080ti, no overclocking right now to test this issue though I do have Afterburner up which does hook in an overlay I suppose
16 GB DDR4
i5-6600k @ 4.7 ghz
Install is on a NVME drive
Nvidia 385.28 Drivers
The system is pretty vanilla, I dont like a lot of background processes. I do have Teamviewer autorun but I’ll shut it down and there is no difference.
I was interested in the Intel iGPU workaround but I actually have mine disabled completely in the BIOS and it doesn’t register as a device in Windows at all.
I’d like to resolve this because its so bad on occasion its game breaking
I also share the same symptoms, a crash which happens randomly after an alt tab with a fixed window EVE client.
I will try to use the fullscreen mode, but the fixed window mode is quite nice to have if you have to play with multiple clients at the same time.
I already tried to disable the game mode of windows etc, with no results so far as the crash still happen from time to time.
Since October, did you found a solution for your issues ?
