System log from the timeframe of screen wake

SUMMARY
This issue occurs after waking the screen after it has turned off (due to Screen Energy Saving) - *not* from Suspend session (when manually putting computer to sleep). Some application windows (though not always all) seem to disappear. The application is still running and its icon is still in the Task Manager. However, clicking the application icon in the Task Manager does not bring the window into view. 

I end up needing to close the windows from the Task Manager (window preview pane shows blank window as well). Then I can re-launch the application.

I see in the system log (attached), that there is this message from the time when I wake the screen:
kwin_wayland[14813]: libkwinglutils: Invalid framebuffer status:  "GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT"

STEPS TO REPRODUCE
1. In System Settings, Power Management, Energy Saving, enable Screen Energy Saving and set time to some value < Suspend Session time.
2. Wait for screen to turn off as per time set in step 1
3. Wake the screen by pressing key on keyboard

OBSERVED RESULT
Some windows that were open and visible before the screen turned off - such as Konsole - are no longer visible. However some other windows are unaffected - such as Firefox. I'm unable to find a pattern as to which windows will disappear and which won't, but Konsole seems to be reliably reproducible.

EXPECTED RESULT
All open and visible windows before the screen turned off should be present when the screen turns back on.

I took this screenshot, then waited until the screen turned off

This is what my screen looked like right after waking it. All my windows have disappeared.

After screen wake 2

There was a crash report from System Settings, and you can see that other applications that were on screen prior to the screen turning off (Konsole, KWrite) are still running in the Task Manager. However, the window preview is blank, showing the window is gone.
Comment 4 Yosuke Matsumura 2022-11-17 16:04:46 UTC 
Updated system to following versions; issue still remains:

KDE Plasma: 5.26.3
KDE Frameworks: 5.100.0
QT Version: 5.15.7
Comment 5 Zamundaaa 2022-11-22 14:24:10 UTC 
When it happens, can you open the kwin debug console (search for kwin in krunner) and check the geometry field for the disappeared windows, if they're offscreen or resized impossibly small, something like that?

Hi, I've uploaded screenshots of the Kwin Debug console, opened to the Konsole windows that has disappeared.

Couldn't be weirder but that explains why you don't see the window anymore
Comment 10 Antoine Gatineau 2023-03-12 08:40:21 UTC 
Hello,
I am also having this issue. It is still present in 5.27.2
Operating System: Fedora Linux 37
KDE Plasma Version: 5.27.2
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.1.15-200.fc37.x86_64 (64-bit)
Graphics Platform: Wayland

However sinc e5.27 the window can now be recovered by focusing, defocusing, refocuing the window (click on the app in the task manager)
Won't work if multiple windows are grouped in task manager.

If any debug output or testing is needed, please feel free to ask
Comment 11 Antoine Gatineau 2023-03-12 13:13:27 UTC 
Something that might help.
On my laptop, in don't have the issue. It's configuration:
Operating System: Fedora Linux 37
KDE Plasma Version: 5.27.2
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.1.15-200.fc37.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i7-8565U CPU @ 1.80GHz
Memory: 15.4 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620
Manufacturer: ASUSTeK COMPUTER INC.
Product Name: ZenBook UX433FA_UX433FA
System Version: 1.0

On my desktop, it is pretty systematic when waking up the screen (single screen). It's configuration:
Operating System: Fedora Linux 37
KDE Plasma Version: 5.27.2
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.1.15-200.fc37.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 1600 Six-Core Processor
Memory: 15.6 GiB of RAM
Graphics Processor: AMD Radeon RX 5700 XT
Manufacturer: Micro-Star International Co., Ltd.
Product Name: MS-7A39
System Version: 1.0

The desktop has a 4k resolution but event in 1920x1080 the issue is present.
So it looks like an issue with AMD GPU.

before sleep with quick tiled windows

After upgrading to plasma 6 on Fedora 40 Beta, the situation is much better.
Operating System: Fedora Linux 40
KDE Plasma Version: 6.0.2
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2

Graphics Processor: AMD Radeon RX 5700 XT

Product Name: MS-7C91
System Version: 2.0

The issue appears to be fixed for floating windows. I just ran a few sleep/wait/resume and the windows come back with the original geometry.
However the geometry changes when windows are quick tiled. (which is my regular way of organizing my windows :/ )
The title bar comes back to a original (default) size and the body of the window either keep the pre-sleep size or reverts to an original size matching the title bar.

I hope this helps to pinpoint the source of the issue.

placementtracker: fix quick tiled windows not being restored correctly

There were two problems:
1. Workspace interacted with the tile mode of windows before inhibiting
the placement tracker, so the wrong window state was stored in the placement
tracker
2. Window::setQuickTileMode is unintuitive and has some undesired side effects,
meant to handle quick tiling with keyboard shortcuts and by dragging the
window with a mouse specifically. This commit just works around that by
un-setting the tile mode first
