No imgui menu on Linux
raedwulf opened this issue · comments
I cannot seem to get the IMGUI to show up in the examples - although the rendering seems to mostly work here.
I've tested it both on Intel and AMD gpu hardware with mesa-21.0.3.
sorry for late reply
But I just tested on ubuntu + nvidia drivers and it seems to be alright:
Also check for imgui-*.ini file patterns in your rizz bin directory and delete those.
could you provide more information, like the log for example ?
Ah, drawsprite seems to fail completely:

Segmentation fault
Occasionally animsprite fails...
damn, this is weird. and I don't have anything remotely similar to your distro/driver setup to test it out myself.
you can try out debugging it yourself, for the profiler assert, try disabling it with cmake flag ENABLE_PROFILER=0
As for the error in drawsprite, it comes from not initializing/loading textures properly, most likely in rizz__texture_on_load or rizz__texture_on_finalize functions.
First you should pull the latest, I added new assert to catch texture loading assert checks. Then you can run it through the debugger and capture the callstack and more details on the error.
I'm sorry that I can't help more than this
Okay, I'll see if I can debug more when I have some time. As far as I know, normal imgui examples do seem to work fine on my system - I wonder if it might be something to do with Mesa GL differences, since I guess you've only tested it on Nvidia drivers?
yup. I can probably test with nouveau drivers some time, but don't have the time now
I'll get back to you if I can reproduce with llvmpipe.
It also has problems with the mesa software renderer:

*** stack smashing detected ***: terminated
Segmentation faultthat should be another issue. for now, use -DENABLE_PROFILER=0 to disable the profiler completely
Sorry for the delay, I disabled the profiler and I have the same the exact same errors with the software renderer too.
Edit: I mean the above errors with no UI + image size error and not the Segmentation Fault / stack smashing.
what do you mean by "software renderer" ?
btw, the profiler crash should be fixed by now, it was a regression bug from remotery which I reverted it back to previous version

Sorry, I meant the mesa software GL rasterizer, llvmpipe. It has similar behaviour as the other Mesa-based gpu drivers so it might be possible to reproduce it on your system more easily (or even in a VM).
https://docs.mesa3d.org/drivers/llvmpipe.html
It is normally enabled with
export LIBGL_ALWAYS_SOFTWARE=1
But this doesn't work with nvidia proprietary drivers. You'll need to have Mesa enabled (perhaps with nouveau). I suspect a VM might be just as easy through QEMU but I don't know the steps off the top of my head. VirtualBox is a bit more finnicky because they have their own GL driver/wrapper thing.

Great! 👍
since I can't reproduce the issue and the author didn't investigate the problem furthor more, I will close this for now.
