Enable input control crashing OBS

[MakiMakoTaco]

Describe the bug
Under the configuration options Enable Input Control is ticked and whatever I do, I can't uncheck it including deleting and re-installing/installing a different version. I think this being checked also lags my PC for a bit when OBS is opening but that's not a huge issue and could just be my PC. OBS also crashes when I just try and add an input overlay, I don't know if this is because of Input Control being checked but it happens anyways.

io-client also seems to crash on open too

To Reproduce
Steps to reproduce the behaviour:

• Uncheck Enable Input Control and click OK
• Open up the configuration menu and click OK
• Add an Input Overlay
• Open OBS (for the lag),

Expected behaviour
OBS to not crash

Screenshots
If applicable, add screenshots to help explain your problem.

Additional information:

• Plugin version: 5.0.4 (I think this started on 5.0.3 and I emailed Universal a few months ago but I didn't hear anything back)
• Full OBS Studio log: https://obsproject.com/logs/I3piiC0JGIOpt4qN

Additional context
I'm not completely sure if it is a crash but OBS doesn't respond and I've left it for about half an hour with OBS still not responding. The one time I somehow got an input display visual without OBS crashing I couldn't resize the display, it originally showed the resize cursor and I dragged it but nothing happened and then I couldn't interact with the display after, and it didn't seem to actually work.

Do you have a crash log? Are there any filters for the input control setting?

To reproduce on my machine each time, follow the clicks:

• Tools
• input-overlay settings
• Enable Input Control
• OK

I need a crash log. Run gdb obs -ex run, answer no if it asks to download some debug symbols, make it crash, run bt in the gdb shell and paste the result here

Can you also upload a log file of obs studio? Also which AUR package are you using, there seem to be three different ones.

[agilob]

obs-studio from extra (not aur) https://archlinux.org/packages/extra/x86_64/obs-studio/

obs-plugin-input-overlay 5.0.5-1 from aur https://aur.archlinux.org/packages/obs-plugin-input-overlay

Ok, maybe new issue now. Somehow my obs completely broke and couldn't after in "Normal Mode" after a few more crashes. I was forced to uninstall, remove .config/obs-studio and .local/share/obs and install all again. input overlay is still crashing as before, but I see different traces now. obs.log is with gdb, obs.log is without gdb

obs.log

obs2.log

I can't seem to reproduce the issue but I just saw that you're on wayland so that means you won't be able to use the plugin (and input filters) anyways. The only thing that (probably) should work is the gamepad hook.

[MakiMakoTaco]

I can redownload and do anything you need for info but all I remember is that Enable Input Control was originally turned off, I turned it on when looking around at things. That's when it then first crashed, I tried unchecking it after reloading OBS and it would just crash everytime I tried to confirm it and leave the checkbox ticked including uninstalling and reinstalling. I think I went into the files and tried manually turning it off too which changed nothing.

And then as I mentioned in the original message doing anything in OBS it would either lag (including moving the mouse) or if I tried doing anything related to input display it would crash

[univrsal]

Yeah, I didn't mean your original bug report. The issue @agilob reported is unrelated to yours and it's not an issue that can easily be fixed. I don't have a Windows installation around right now but when I get some time I'll try reproducing your bug report and then I'll see if the bug still exists and what the cause is.

[MakiMakoTaco]

Ok no worries, thanks

[escapetheory]

I am having the exact issue that MakiMakoTaco describes. No amount of clean plugin installs (using the .exe and manually extracting the files) fixes the issue and OBS just crashes if I try and untick this option. :(

[univrsal]

I still need a crash log. OBS should give it to you after the crash.

[the-paid-actor]

Same situation with me. But to be precise OBS doesn't crash, it just hangs, and then I have to kill it through windows. That's why there is no crash log for OBS. After reopening OBS, mouse freezes for a couple seconds and OBS behaves weird, and the checkbox cannot be unticked without OBS hanging. Only solved after deleting the input-overlay lines on obs appdata global.ini.

As far as I can see "input control" is just a regex over open window names to enable overlay to work only under whichever window I specify right? I took a quick look at the code and I can't find anything obvious of why there would be a problem... maybe something with the mutexes there? If I have time I will try to debug it on my machine (I'm a software dev)
