Bug#988016: prboom-plus: Segmentation fault on Wayland

[Chris]

Package: prboom-plus
Version: 2:2.6um-1
Severity: important
X-Debbugs-Cc: mode4torque at tutanota.com

Dear Maintainer,

On sway WM with "xwayland" disabled, prboom-plus seems to work fine, I
can configure options and play a game. However, once I quit, I get
the error:


I_SignalHandler: Exiting on signal: Segmentation fault
Segmentation fault


after which the configuration file "~/.prboom-plus/prboom-plus.cfg" gets
cleared (not deleted, but completely emptied) and all settings are lost.
I can reproduce it every time, fullscreen and OpenGL/software rendering
for example do not matter, even if I start fresh with no config file and
immediately quit.

Once I enabled "xwayland" and restarted sway, the problem is no more.
Segfault suggests it has to do with the way it draws the screen which
was fine on Xorg but not on Wayland.
