Before that I had never faced this issue. I had installed lutris before the update to firefox 123 and removed it (lutris) and its dependencies after some days. After that when I tried to install firefox I am facing this issue. I don't think this has some connection but multiple packages were upgraded to support 32 bit when I installed lutris and when I uninstalled I made sure they were switched back to supporting only 64 bit as it was originally done before installing lutris.
Since, this was a major change I did, I thought it might have something to do with the compilation error.
There is also a bug raised for this on firefox 123 : https://bugs.gentoo.org/925101
But not much progress it seems.
Any idea what could be the issue?
I have a very identical system to the user on whose system the build is not failing as mentioned in the above bug. https://bugs.gentoo.org/attachment.cgi?id=887474&action=edit |

I did do some research on WebRender and what is its functionality. If Webrender is moved to CPU, instead of GPU (Webrender does not always use GPU) wouldn't there be a significant performance impact. Isn't this what hardware acceleration means?
So, basically all this patch is doing is making sure any hardware acceleration is not used even though enabled as rendering is now done by CPU? Correct?
If this is all it does, I would sacrifice the PGO and its performance gain(5%). |

To a some degree, yes. But PGO is not just about your GPU or graphical rendering, you may look here for more information.
If you really want the performance boost, it is still there. In my honest opinion, for daily usage the difference is not worth the double compile time, but that's a different topic

Hi Kresni,
Thanks, for the article on PGO. Given, that the patch is the only way to get PGO build working, I think I would settle for a build without PGO for now given the performance gain for the build time, I feel, is not worth it.
What is really bugging me is that mozilla official build use PGO, and if a build (firefox-bin) exists, how are they compiling it without issues? Certainly, they are not using the patch as that would cause hardware accel to never be used. I have cross checked with the source code for version 124.0.1, this patch is not applied. |

This is something that I thought about as well. As they are the ones that wrote the software, they probably have a workaround to make it work with pgo, but it looks like they did not make that information public?
I have seen some package maintainers on other distributions struggle as well, very weird.
