Zed (with WGPU) consistently hangs for long periods

[alonsoC1s]

Reproduction steps

1. Start Zed
2. Open any text file or open log
3. Insert text

I had previously reported a similar issue #47750, which was going to be resolved by PR #46758. After uninstalling and cleaning the residue from Zed, I installed the newest version, hoping that the issue was resolved. Sadly, it persists. I'm not sure if the cause is the same, but the migration to WGPU has apparently not affected the end result. This is even more strange, given that my current setup is very different from the original. It includes a discrete GPU and X11 instead of Wayland.

Simply scrolling text freezes the editor, which makes it functionally unusable.

Ouch, sorry to hear that.

Unfortunately, I think this may have to do with the GPU detection logic.

I know it might be a hassle, but does the problem persist if you only use a single GPU? If not, which combinations are problematic?

Thanks!

I have the same trouble with same graphic card.
OS: Nobara Linux 43
Desktop: Gnome
Graphic cards: Intel Corporation CoffeeLake-H GT2 [UHD Graphics 630]; NVIDIA Corporation TU106M [GeForce RTX 2060 Mobile] (rev a1)

I am experiencing a similar problem on a 2-GPU desktop with Intel Haswell integrated (driving screens) and AMD Polaris discrete.

Something about powering up the dGPU causes the whole machine to freeze for several seconds. It's not a Zed-only problem. I can reproduce it with VK_LOADER_DRIVERS_SELECT='*radeon*' vkcube. There is a desktop-global pause of 5-10 seconds before the window opens.

The way that Zed exacerbates the problem is that it wakes up the dGPU again every time the Zed window regains focus and renders its first frame after a long time idle (enough for the dGPU to power off; can be seen in /sys/class/drm/card*/device/power/runtime_status).

I think it might have started with a recent kernel upgrade? I haven't tried booting into the old one yet.

A workaround that works on my machine is launching Zed with

flatpak run '--env=VK_LOADER_DRIVERS_SELECT=*intel*' dev.zed.Zed

I'm probably going to keep that going forward, since Zed has no reason to be using discrete graphics and costing an extra 15-20W constantly. (To make permanent, flatpak override --user '--env=VK_LOADER_DRIVERS_SELECT=*intel*' dev.zed.Zed).
