--- Comment #46 from Andrey Rakhmatullin ---
Not sure if it's this bug, #400921, something new or something I didn't find in
the BTS but on my dual-monitor setup with HiDPI the screen gets turned black
when using the spectacle selection. Disabling the second monitor in kscreen
makes the bug disappear so it's similar to this bug but black screen as opposed
to some corruption makes it similar to #400921. And it worked on earlier
software versions but it's hard to say when it broke as I upgraded from a
couple years old configuration before noticing this. The configuration details
are below.
Software: today's Debian Unstable, Spectacle 23.04.2, Plasma 5.27.10, X 7.7, Qt
5.15.10, nVidia drivers 535.86.10.
Setup: a desktop nVidia card with a 2160p monitor on DP-4 and a 1080p monitor
connected on HDMI-0, with a "{viewportin=3840x2160,
ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}" xorg.conf
incantation scaling the 1080p one to match the 2160p one. And the global
scaling in kscreen is set to 200%.
What happens: when I start the selection mode in spectacle, the 1080p monitor
gets the usual gray overlay but the 2160p one gets fully black, with the
spectacle UI correctly drawn on top of that. But if I disable the 1080p one in
kscreen and start spectacle again it works correctly.
