Status changed to 'Confirmed' because the bug affects multiple users.

[Gert van de Kraats (gkraats)]

I created bug #1795760, which describes a Xwayland-abort and got the status duplicate of 1745799.

Below is a part of the symbolic trace of the abort.

 #7 0x004b6296 in xwl_log_handler (format=0xb7dc71ea "%s@%u: error %d: %s\n", args=0xbf9c7994 "\027uܷ\255\001") at ../../../../../hw/xwayland/xwayland.c:1137
         msg = "wl_surface@429: error 2: Failed to create a texture for surface 429: Failed to create texture 2d due to size/format constraints\n", '\000' <repeats 127 times>
 #8 0xb7dc5fef in wl_log (fmt=0xb7dc71ea "%s@%u: error %d: %s\n") at ../src/wayland-util.c:404

Problem can be solved by using slicing at shm_buffer_attach() at src/wayland/meta-wayland-buffer.c, if size of texture is too large for graphics card.

I attach a bug-fix to this bug, which is tested during a long time.

Gert,

I agree bug 1795760 is different. It has been unmarked as a duplicate so maybe use that instead?

[Aurimas Fišeras (aurimas-gmail)]

Package from jammy-proposed crashes with the same stack trace: xwayland 22.0.99.902-1

[Aurimas Fišeras (aurimas-gmail)]

I can reproduce the crash reliably in less than 1 minute by simply repeatedly drawing rectangles on the empty black background (using JOSM plugin https://wiki.openstreetmap.org/wiki/JOSM/Plugins/BuildingsTools) in JOSM.

[Aurimas Fišeras (aurimas-gmail)]

I can reproduce the crash on 3 different notebooks:
 1. Lenovo ThinkPad P14s with AMD Ryzen 7 PRO 5850U with Radeon Graphics
 2. Lenovo ThinkPad T480 with Intel i7-8550U with integrated Graphics
 3. Lenovo ThinkPad x220 with Intel i3-2310M with integrated Graphics

It doesn't matter, if external monitor (or two) is connected, or not, if scaling is enabled (125% or 200%), or not - crash is reproducible every time.
