Video showing 2 monitors a few applications started and how the display hangs when pressing toggle overiew
Sorry, I don't see how to edit the previous message, but I am using Wayland not X11 Your hardware is powerful; this definitely shouldn't be happening. For what it's worth, I have similar hardware (7940U, everything else the same) and toggling overview with animations disabled is 100% instant for me. Is it any better with animations turned on? Does it work as expected in a new clean user account on the same computer? > Is it any better with animations turned on? Well... Depends. Setup: - Still running the same session as when the attached clip has been recorded (laptop has been running 11hours) - Laptop display out (I have disconnected the external display) - power plugged in, everything is set to max performance (same as before) - 2 "browsers" streaming videos at 1080p - Animations set to instant. Toggling overview is not great, about 150-200ms but when trying after a few minutes it can be about 500ms, not pleasant. CPU usage only spikes on a single core to ~45%, also checked the nvme performance it is not being a bottleneck. Testing with Animations speed set 8th step (from the left): - About 800-900ms of frozen screen when it unfreezes i instantly see the overview view. >Does it work as expected in a new clean user account on the same computer? Do you mean a new user or a clean install? A new user account. A clean installation would be a bit of an invasive thing to ask you to do! Though if you can (maybe with a live session via a USB flash drive) that would be useful information to know as well. Basically, anything to narrow down what might specifically might be causing this, especially because I can't reproduce it with almost identical CPU and GPU hardware, which points away from the idea of it being a GPU driver issue or a general code issue with Overview. One thing I haven't mentioned is that it doesn't happen from startup, it happens after running for some time. Same device: After reboot, running for 58mins couldn't replicate (100-150ms toggle overview). Same device, new user after maybe 15 minutes couldn't replicate (100-150ms toggle overview, tried dual monitor also). Thinkpad x270: liveboot couldn't replicate the issue in a few minutes. (100-200ms toggle overview) Huawei D15: liveboot couldn't replicate the issue in a few minutes.(100-200ms toggle overview) I don't know how to replicate the issue, but I had it happen quite a few times - just that today I ran out of patience lol. I will keep an eye out and update when I catch it. One last thing that maybe is related that I noticed that when changing workspace, even if the app on for example is on workspace 1 and is placed on the left half, swapping workspace made the application window spawn in a location as if the app was just started and not on the left side. 🐛🧹 ⚠️ This bug has been in NEEDSINFO status with no change for at least 15 days.
