--- Comment #3 from Gianandrea <asubstan...@hotmail.co.uk> ---
I have seen a similar issue to this when running KDE 6 - Beta 2 pulled from
this COPR https://copr.fedorainfracloud.org/coprs/solopasha/kde6/ into my
Fedora 39 system running Nvidia. I additionally have explicit sync patches
applied for Xwayland and Wayland-protos as provided from the Nobara Project
COPR.
I do not actually have this problem with KDE 5.27.10 (evertything else the
same) only when switching to KDE 6 - Beta 2 as noted above. I haven't reported
it as my setup was obviously not setup in an ideal fashion for testing. However
I mention it as I have a similar setup with similar results when using Beta 2
in case it helps triangulate the issue. It might be revealing that it doesn't
happen to me as an Nvidia user in 5.27.10 but does in 6 beta 2.
I tried enabling disabling other settings and these did not affect the issue.
To note VRR does not enable as I run the DP to HDMI adapater due to bandwidth
limitations on the HDMI port.
Issue:
"When using a display port to hdmi adapter there is also a blank screen/black
screen effect."
For me the issue is actually only this element, but consistently if I have the
resolution at 3840x1600 and 120hz. It mostly occurs when opening a new
application, or opening the start bar. If I watch a video or do anything in an
already open window I don't have an issue. Also games will run totally fine.
Hardware:
Nvidia 2080
Samsung QN90B set at ultrawide 3840x1600 - DP to HDMI 2.1 converter
Denon AVR-2500HX - HDMI for sound
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 39 6.6.0.5-amd64
(available in About System)
KDE Plasma Version: 5.91.0
KDE Frameworks Version: Did not check before reverting
Qt Version: Did not check before reverting
