[3.5.0, Debian Stretch] Lockup whenever initializing window

[Matt]

Things seem fine in fullscreen so far, but the game immediately becomes totally unresponsive if I try to switch to windowed or try to start windowed (the window will appear but inside will be just garbage - not random tutti-frutti but, say, if I switch desktops and switch back that area still shows what was showing in there on the previous desktop). If I try to switch to windowed the music continues playing in the background but I don't hear any switch sounds hitting Escape so I assume it's not just the video failing to render.

No crash log, I just use the kill command to get out of GZDoom. CPU and RAM don't start spiking when this happens and I don't notice any slowdown on my computer, so it's not a loop or anything.

I have tried this with my usual ini and starting from scratch (with only an edit to let it know where my IWADs are).

Setting up a Debian machine right now to debug this. Hold on.

This might be SDL 2.0.4 related (or whatever old version Debian uses).

[_mental_]

Ubuntu 16.04 is using SDL 2.0.4 too but windowed and fullscreen modes work fine there. This can be desktop environment related problem. Matt, which one are you using?

EDIT: Also, Stretch is using SDL 2.0.5.

[Marisa the Magician]

Ah, I noticed. I set it up with LXDE and there don't seem to be any issues, so yeah, please tell me what DE you have.

[Matt]

SDL 2.0.5 and OpenBox

[Marisa the Magician]

Weird, I've used openbox all my life and never got such an issue. What about your GPU and drivers? Do you use a composite manager, too?

[Matt]

GeForce GTS 450, nVidia driver 384.130-1, no compositing.

[Marisa the Magician]

welp, time to run this on bare metal

[_mental_]

What options should I choose on the following screen to match your setup?

[Matt]

..... no idea, sorry

It's actually a CrunchBang install from ~2013? or so where I got rid of the #!-specific stuff when the distro was discontinued and upgraded to Stretch (and had previously upgraded to Jessie) via editing sources.list. I never saw that menu and would have gotten OpenBox built into the initial installation.

[fakemai]

First I just did a quick check on my system since it's Debian Stretch and Openbox happens to be loadable the same way I do Xfce. Couldn't reproduce the issue but I'm on much older Intel hardware and using the legacy branch. I would say it's probably dangerous to be mixing distros like that, even if they're from the same family, unless you mean you did a clean reinstall.

[_mental_]

This problem is specific to the modern version only.

Unfortunately without the way to reproduce the issue, we cannot fix it.

Let's ask this, the most pertinent question of all:

@Matt: What happens if you dual-boot to a clean Stretch install and run GZDoom from there? Even if you copy your /home folder over, and only the fewest necessary files from /etc?

[Matt]

> boot

Could be a while before I can free up a weekend to do that... I'll try to poke around some other settings in the meantime but it might be best for everyone else to leave this alone unless and until I manage to isolate the problem further.

[Matt]

Whatever was going on, it has been fixed as of the release of GZDoom 3.6.0, thanks!
