Description

Created attachment 139220 weston stderr output

When running weston-launch from a terminal, I get a freeze when the mouse pointer is moved to the left edge of the desktop. The desktop freezes, I can still use ctrl-alt-backspace to exit weston. The mouse is frozen and all screen drawing is frozen. This does not occur on the top right or bottom edges.

This seems to have been introduced since updating to weston 4.0.

I am running a standard arch Linux x86_64 (fully up to date) on an Intel Cherrytrail PC box. There is no weston.ini file so all configuration settings are defaults. Gnome, KDE, X, etc are not installed, just Wayland and Mesa.

I can reproduce every time as follows:

on a console terminal: weston-launch --verbose 2>weston.log <enter>

Move mouse over to left hand edge. Everything frozen. Press ctrl-alt-backspace to exit or kill process.

Any program like weston-simple-damage also freezes.

There is a line in the log that is output when weston freezes:

atomic: couldn't commit new state: Invalid argument

I have attached a log file from the stderr pipe.

Some relevant packages installed:

wayland 1.14.0-1

wayland-protocols 1.13-1

weston 4.0.0-1

mesa 18.0.1-1

libdrm 2.4.91-3
