Description Neel Chauhan freebsd_committer 2021-08-13 15:23:05 UTC
On both an HP Envy x360 and a 11" Gateway laptop (2020, but forgot which model) which both use amdgpu integrated graphics, GNOME lags significantly where it's not usable.

This also happens on the Envy with OpenBSD, on both GNOME 3 and 40, unless I use scfb. I don't know about Linux as I only booted non-GNOME-based distros via LiveUSB.

This is an amdgpu problem with GNOME as KDE does not lag on the Envy, with also being able to play Toontown Rewritten via the Linuxulator. I believe it's AMD GPUs as scfb on the Envy and Ryzen desktops with Nvidia GPUs don't lag. I don't know about discrete Radeon GPUs or the older radeonkms driver.

About this phrase:

>This also happens on the Envy with OpenBSD, on both GNOME 3 and 40, unless I use scfb. I don't know about Linux as I only booted non-GNOME-based distros via LiveUSB.

It is unclear. I meant that OpenBSD also lags, but scfb does not.
