VAE decode stops decoding if a instance is idle for a little while with 2.7.10 windows (BMG)

[SHoogstad]

Describe the issue

Steps to reproduce:

1. generate tings
2. wait for a while
3. try to generate again

what I get in the generation process (its an 2 pass workflow) at the last decode it just stops working/decoding (not errors or warning) while if you keep it active it didn't do it this was also not an issue in 2.6.10

if more information is needed let me know!

Thanks for interesting in IPEX.

I cannot a whole picture what happened from this description.
Let me confirm it:

1. The issue cannot be reproduced on 2.6.10+xpu, but happened on 2.7.10+xpu.
2. it's the VAE decode.
   Would you show more information about this?
   the detail steps to reproduce it.
3. After running the workflow, keep it idle for a while, then rerun the same workflow, it stops at decoding?
   What's the workflow/VAE decode is?
4. What windows version (win10/Win11) and version of GPU driver?
5. What's your BMG device type?

Please provide me the information, so that I can reproduce it.
Thanks!

its in an issue in diffusion models like SDXL(stable diffusion xl)

let me give you a little more info:

1. yes
2. its encode not decode mis wrote it sorry about that here is the code its bassicly converting latent to an actual image
3. just as i said just leave it idle no diffusion going on or something for like 10m then encode just stop working
4. win11, driver 32.0.101.6647
5. XPU b580 12gb
