Developer file preview

Steps to reproduce

Ok. I can reproduce this within VM by selecting different files fast (clicking around from file to file), PT v0.55.2

Edit: Looks like machine performance plays a role for reproducing

I think this was my scenario, i ran into the issue when rapidly clicking between a couple files and quickly opening one. My bet is weirdness with the preview pane lifecycle.

@Hofferic / @oguh43 / @PromanSEW / @888iee / @GetzzY Few questions:

  • How often does this occur? (Daily basis, etc…)
  • What files are causing this? (Please attach the file or email it to us if possible. If there is multiple files, please zip it first. )
  • Can you please send a screen recording of when this occurred?

Thank you in advance.

  1. It happens when I quickly drag-select multiple-files in a “File Open” dialog (notably when I do “Add \ Existing item…” to a filter in VS2022)
  2. Not sure.
  3. Heh, now that I tried to reproduce it, couldn’t 😦

EDIT:

finally, here’s the stack trace (no gif), same thing: selecting multiple files in the aforementioned “file open” dialog (be warned, it’s pretty long)

************** JIT Debugging **************

Sorry, no JIT info, i have it turned off, as it was getting annoying trying to debug everything in my system 😦
(the intel management ui, or intel DPC++/C++ compiler’s installer, the windows configuration designer, the SDK previews or simply the windows store crashing, or anything throwing/logging an exception every 10 minutes 😕

Is this perhaps related to having many files selected?

Maybe. But why does this happen in dev file preview. And not other preview handlers?

Dev file preview is a bit more complicated, due to the extra thread handling. That might be related. Have you replicated this?

I can reproduce this. I’ll try debugging it.

I can’t debug it with VS 2022. I always get a DRIVER_OVERRAN_STACK_BUFFER bluescreen when attaching it to prevhost.exe and I have no idea why. IMG_20220210_195808.jpg
