--- Comment #48 from Matija Šuklje <mat...@suklje.name> ---
I can confirm this issue persist in:
Operating System: EndeavourOS
KDE Plasma Version: 6.1.5
KDE Frameworks Version: 6.6.0
Qt Version: 6.7.2
Kernel Version: 6.10.10-zen1-1-zen (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 5700U with Radeon Graphics
Memory: 30.7 GiB of RAM
Graphics Processor: AMD Radeon Graphics
Manufacturer: SLIMBOOK
Product Name: PROX-AMD5
If it is relevant:
- my laptop’s screen is 1920×1080 @ 60 Hz (see above)
- my external screen is 1920×1080 @ 144 Hz (AOC 24G2W1G4)
I can replicate it both when clicking full-screen (or pressing `f`) in YouTube
and Invidious on Firefox, in full-screening Haruna and starting the
presentation mode in LibreOffice Impress.
As a...@stronzi.org said, it seems to be connected to VRR (Variable Refresh
Rate).
By default in Plasma’s SystemSettings VRR is set to “automatic”, which as
described in this bug report, seems to trigger the black screen when something
goes full-screen.
I can also confirm that setting VRR to “never”, works around this bug.
Then I also tried to set VRR to “always”, which right away blacked out my
external screen. Which is why I’m quite confident VRR has something to do with
this bug.
