Here is a video: https://e.pcloud.link/publink/show?code=XZPwoeZbm8XvysprWfDOHPhFuTJnbKAzjp7

It's working perfectly fine for me on Plasma 5, this is what I experience on Plasma 6 RC1 & RC2

I spun a Fedora 40 VM this morning and the issue is present on fixed and floating pannel. I have added screencaptures.

I am unable to reproduce this with the master and release/24.02 branches of Spectacle.

vm-rc2-screenshot

I can still reproduce this on the VM (Fedora 40 with Plasma 6 RC2), see screenshot. I don't have it installed on my laptop with Intel graphics, so I cannot double check there, I've tried live USB with same image on my AMD GPU-based Desktop and the issue is not there, so I guess it depends on the gpu driver in use.

The VM I use is qemu with kvm, llvmpipe for graphics. I have a feeling it has something to do with the floating taskbar, it feel like it tries to defloat on screenshot and maybe there is a race condition: screenshot rectangles gets drawn, then the taskbar defloats and is drawn on top of that?

Race condition is a plausible theory. I'll have to keep an eye out for that in case it's true.

Just tried RC2 from the live usb on same Intel laptop from the original report and it's still reproducible

Huh, now when I look at those screen shot you can actually see there are double frames for the panel: the floating one is still there and then there is a defloated one

amd-desktop-rc2

Okay, never mind my GPU driver theory, probably it was an earlier build that worked or something else was different. Here is it's also reproducible on a desktop with AMD GPU. Given the early screenshot it wasn't visible that the panel is different, maybe with later builds it became more apparent that there is state change during the screenshot, basically area capture is treated as a full screen app for a second.

It is a fullscreen app with a window for each screen since Spectacle 23.04.

There is something very odd happening: I've booted my existing F39 with 5.27.10 and spectacle 23.08.5-1.fc39 which we just got this week in Fedora testing and the issue is there, however I've downgraded it to the previously available 23.08.1-1.fc39 and the issue didn't reproduce, I've upgraded the package back and it was still working. I've rebooted afterwards and now it's not working neither with old version, nor after kicking package version back and forth. That's on my AMD Desktop system

If you're able to click on the panel normally when spectacle is doing a rectangle capture, then it's probably not a GPU issue.

I#ve the same issue. It happens when I scale my screen size down to 75%.

I don't know if it is the same bug, but for spectacle 24.08.1 and Plasma 6.1.5, whenever I try to select a rectangular region, the screen goes black and I see nothing.

Using Tubleweed.

I have integrated AMD graphcis.

I'm using Wayland.

Different bug. Yours sounds like bug 493222.

Is the original bug here still reproducible for anyone? I cannot reproduce it.

I still saw the issue few weeks ago, it got more consistent (as in it generally works), right now does not reproduce with latest versions of everything, let me go over my devices (amdgpu, intel gpu, arm mali gpu) and see where we stand with the latest stack. I just got all my devices to Fedora 41 beta with fresh mesa.

Tested on following software configuration:

Operating System: Fedora Linux 41
KDE Plasma Version: 6.1.5
KDE Frameworks Version: 6.6.0
Qt Version: 6.7.2
Kernel Version: 6.11.0-63.fc41.x86_64 (64-bit)
Graphics Platform: Wayland

Worked as expected with amdgpu (RX 7900XTX), i915 (Intel UHD620 on Lenovo P1 gen2), Pinebook Pro. Works with both floating and non-floating bar right now. I guess we can close it as it was fixed at some point recently.
