X error with intel device #11

Closed jspanchu closed 2 weeks ago

jspanchu commented 1 month ago

On an intel gpu, I get an X error from glfwPollEvents() during the second iteration of the infinite loop.

X Error of failed request:  136
  Major opcode of failed request:  148 ()
  Minor opcode of failed request:  1
  Serial number of failed request:  274
  Current serial number in output stream:  274

The opcode details:

xdpyinfo -queryExt | grep opcode | grep 148
    Present  (opcode: 148)
Kangz commented 1 month ago

Could you add a call to SynchronouslyDebugX11() in Surface::Surface? It could help give a stack trace and lead to maybe a a root cause.

jspanchu commented 1 month ago

Good to know there is a function for that.

However it doesn't bring up any new clues. I was already aware that the issue occurred during glfwPollEvents.

Edit: updated stack trace after installing x11 debug syms

Kangz commented 1 month ago

At least we know that it is something done in glfwPollEvent itself and not a problem that's queued and only found in that function. I really don't know why "Present" would file then though :/

beaufortfrancois commented 1 month ago

@Kangz Shall we file a Chromium bug for this?

Kangz commented 1 month ago

TBH I don't know that we'd do anything, it seems to be between glfw and X11? Presumable that's not with the Dawn backend so IDK what we could do.

jspanchu commented 1 month ago

I could try without glfw and check if it still reports the same error

beaufortfrancois commented 2 weeks ago

Shall I close this issue?

jspanchu commented 2 weeks ago

yup, fine by me.
