I use OO on a laptop.
During the day, it is plugged on a video projector (duplicate display of the screen).
During the evenings, I plug it on an HDMI screen (external screen only).
In the meantime, I hibernate my computer.
I keep the files opened as long as I need them.
Quite often, when a file has been opened for a while (and gone through several hibernation & change of display resolution of the computer), after a while it is impossible to display it anymore.
At first, when I try to display it by clicking the thumb view in the Windows task bar, nothing happens.
Then, if I display the files thumbviews, the one for the file is blank:
The only solution I have is to click the window, then do ALT+F4.
There I get the “do you want to save the file” pop-up, I can save the file.
The file is ok and can be opened again.
Note that not all the OO windows are affected at once.
As you can see on the screenshot, other file are perfectly usable.
In my opinion, there is a glitch in the display functions of OO which sometimes does not handle correctly the hibernation of windows (it is when I wake up the computer that the problem occurs).
I have few more questions that would help us in troubleshooting the issue:
Does it happen to any file formats or PPTX like on the screenshot in particular?
Did you face this issue when there was only one file opened at a time?
Did this issue occur when laptop was connected to a wall?
as far as I remember, it also happens with the word processor (but I use it far less, so it occurred less times)
not that I remember
what do you mean by "connected to a wall ?
If you mean the power supply was connected, the answer is yes (I seldom use my laptop without plugging it to an electrical socket).
If you mean “connected to a screen”: it happens when my computer is connected to an external screen (laptop closed) or a video projector (duplicated screen) or not connected.
Funny : after having written my previous answer, I just needed to use a docx file which was opened.
I clicked the thumbview, nothing happened.
So I had an idea : I opened my laptop without disconnecting it from the external screen.
Guess what : the docx file was there…
What is not normal is that when I close my laptop, all the active apps are “moved” to the external screen. All but some OO windows.
So I think here is the bug.
Note that this time, the thumbnail of the window of the docx file did not turned “blank”.
So all in all, it looks like the issue appears when the laptop is used with an external monitor and its own monitor is closed, so after a hibernation, when you open the laptop monitor, you the blank/non-functional window, is that correct?
Thinking to the issue, I came to a process to reproduce it systematically:
use a laptop, connected to an external screen, with windows display settings set to “extend display” (sorry for the perhaps approximate translation - I mean when both screens display different things)
put one OO instance on the laptop’s screen
close the laptop screen
On my computer, all the apps “move” to the external screen.
All but the OO instance which cannot be displayed on the external screen, except for a “do you want to save the document” pop-up when you clic the “close” button on the thumnail in the task bar.
If you open again the laptop screen, you find back your OO instance, working perfectly.
Isn’t it related to the issue making the WIN+<- or WIN+ → keyboard shortcuts not working ?
I hope at least one part of the bug is reproducible for you

Unfortunately, we are still unable to reproduce the issue.
Can you please check if the video drivers are up to date and update them if there is higher version is available? After that try to reproduce the issue again.
Is there any particular scenario to reproduce this issue? I just think that if it is not related to hibernation, then I’d be better to create separate topic on this since it does not belong to previously discussed here issue.
