kitty crashes, window manager warnings

[seim1010]

First time opening an issue on GitHub, apologies if I don't include proper information or I do something wrong

I'm finding that after a Fedora upgrade (and a 4K monitor upgrade), kitty terminal seems to be crashing in these types of situations:

• Locking the screen (Meta Key + L)
• Moving kitty to a different monitor, either in Gnome's window management screen (Meta Key), or simply dragging the window around
• I haven't found any other program so far that has this behavior

Here's some information that the contributing guidelines asks for:

kitty version: kitty-0.11.3-1.fc28.x86_64
OS: Fedora workstation: Fedora release 28 (Twenty Eight)
Kernel: 4.17.9-200.fc28.x86_64

kitty config is all colors and font, but if you want to see it:

$ cat ./.config/kitty/kitty.conf | egrep -v "^\s*#|^$"
font_family Envy Code R
bold_font Envy Code R Bold
italic_font Envy Code R Italic
cursor_blink_interval     0

Additionally, some messages I've found in journalctl:

dup of #700

[kovidgoyal]

Oh and post the backtrace from the crash in #700, it might help

Build kitty with

make debug
and after the crash
run

echo bt | coredumpctl gdb

to get the backtrace

[seim1010]

I've cloned the latest repo and have used "make debug". Here's some backtraces @kovidgoyal if they help:

[kovidgoyal]

Those backtraces indicate this is not a issue with XRandR but with the new IME support. You can probably fix the crashes by running kitty with

GLFW_IM_MODULE=none kitty

However, it would be good to track down the cause. See if the commit I just pushed helps. 89b6363

[seim1010]

Well, I wish I knew more about C and building software so I could say something intelligible, but here's another crash dump if it helps. I did clone the latest version of the repo and verified that the commit's code was present:

That stack trace appears to be corrupted. Run

dnf debuginfo-install python3-3.6.6-1.fc28.x86_64

to install the python debug symbols and try regenerating it.

That still looks wrong. Try running kitty from within gdb, like this:

gdb python3
(gdb) r .

That should hopefully get us a useful stack strace.

Hi @kovidgoyal,

I have the same issue as @seim1010.
I am running Arch Linux using Gnome3 on Wayland. kitty crashes, when I drag the window over to another screen and it gets resized (due to different screen resolutions). Maybe interesting to know: it takes a couple of hours until it can occur, before that, everything works fine.

Here some output:
