I have made some changes in /etc/chromium/chromium.conf in version 141.0.7390.65, It could be that this change causes problem in your case.

Could you please attach your /etc/chromium/chromium.conf file here so i can have a look at it?

Thank you!

Thanks for looking into this! Currently it's like this, but I don't know what it was before I downgraded chromium. Should I test upgrading again?

This is still happening for me in chromium-144.0.7559.59-1.fc43.src.rpm

This message is a reminder that Fedora Linux 42 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 42 on 2026-05-13.

Thank you for reporting this issue and we are sorry that we were not

prior to this bug being closed.

This is still present as of chromium-147.0.7727.137-1.fc43. I've not been able to use Chromium ever since I filed this bug report.

I just installed Chromium 147.0.7727.137-1.fc44, 481 MiB in 58 packages, on a test PC with A88X chipset and modestly newer Kaveri APU. It opened up just fine visually to fedoraproject.org/start with user that had never used it before. Note it's running X11 on the amdgpu kernel module rather than the old radeon (enabled via the *cik* cmdline parameters shown by inxi), along with the modesetting display driver instead of radeon. I don't see any visual problems on Youtube or in the forums.

Journalctl is showing a lot of audio-related nasties, but this looks TDE-related, as its builder can't get it built for 44 due to 44's newer gcc version, so this 44 is using the old 43 build of TDE. Running Chromium in IceWM produces no such errors, but neither any sound. :p

Thanks for testing. I'm using wayland and radeon. I tried amdgpu a few months ago, IIRC, and I can try it again if it helps; I won't try going back to X though.

Something else to consider is we both have Gigabyte motherboards with A88X chipsets, so their ages would be rather close if not identical. Yet, my BIOS is 5 versions and 19 months newer than yours, so there might be something to be gained from updating yours.

Yet another: my CPU/APU was available used last month on eBay for under $30USD, and likely still is, along with 2-3 faster CPU models (for more money). 

Still another: my inxi shows minimal CPU activity, while all 4 of your cores are running at 100%.

I've not experienced this issue any more in recent versions, e.g. chromium-151.0.7922.108-1.fc44.x86_64 . I've stopped using chromium though, so I have not tested much.
