SUMMARY
This is an odd one. I recently got this GIANT "57" Odyssey Neo G9" monitor.
Connecting the monitor to my graphics card and leveraging DisplayPort with:
- The full resolution
- 100% scaling
- HDR on
- Displayport 2.1 mode (monitor setting)
- FreeSync Premium On (monitor setting)
- Allow tearing in full-screen windows on
I *SOMETIMES* get variably bad graphical artificating. However, it only seems
to happen when I'm using the desktop. The WEIRD part is if I open a full-screen
game (e.g., Hunt Showdown) the artifacting stops. The EXTRA WEIRD part is that
it also stops on the desktop after the game has been launched and remains fixed
for hours (?) after closing the game.
When the artifacting is happening, I've tried to narrow down what might be
causing the problem by disabling HDR (in KDE), disabling FreeSync Premium (on
the mointor), and by changing the maximum refresh rate in KDE and in the
monitor settings. None of these changes seem to have an effect.
It ALMOST feels like an issue for
https://gitlab.freedesktop.org/drm/amd/-/issues/ but at the same time, the
games work fine. So it's kind of like KWin is doing something funny and some
sort of buffer somewhere is getting corrupted until it's cleaned up by
launching a full screen game (?)
Like I said, this is a REALLY weird one.
