Calc 6.0.6 under Win 10 misses some part of lower, right and left edge. After click, the cell above becomes active.

There are two problems I think they may belong together or stems from a single origin.

I downloaded LibreOffice 6.0.6 a few minutes ago. As I don't know how to display "about" infos, the version ".2 release" is a guess.

Problem 1: After starting Calc under Windows 10 Pro, except for the top edge, there is a small sourrounding area of the window missing. There is no menu visible, even no hamburger menu button. (Hence the version guess.) Look at the attached screenshot.

Problem 2: When I click on a cell, under some circumstances the one above becomes active. "Circumstances" mean: The higher, the more probable. At the bottom of the window, behaviour is unremarkable. At top, there is an offset of more than one cell – meaning, if I click at the top of a cell, even the one two lines higher becomes active. This problem continues in the toolbar area: To expand the font list (below save icon), the mouse must be positioned at about the expand arrow for the cell name list below it. On the other hand, the "+" tool to add an empty table at the bottom behaves as aspected – after all, its in the lower part. Again, the attached screenshot shows the mouse pointer and the activated cell after clicking this very position.

Both problems looks to me as if Calc has got a slighty wrong imagination about the coordinates and size of its window.

"6.0.2" is wrong. I meant "6.0.6".

Thank you for reporting the bug. To be certain the reported issue is not
related to corruption in the user profile, could you please reset your
Libreoffice profile ( https://wiki.documentfoundation.org/UserProfile ) and
re-test?

I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the issue is still present
Comment 3 Peter 2018-08-27 14:23:15 UTC 
Bingo! (At least, somewhat.)

When using safe mode, the problem's gone away.

I addition, I get noticed, that there is some slighty amount of blurrishness in the UI. In safe mode, the UI is more clear.

But what should I do to make it working permanently? Safe mode presents a requester on startup. If I chose "Auf Werkseinstellungen zurücksetzen/Gesamtes Nutzerprofil zurücksetzen" (translates to somewhat like "Reset to factory defaults/Whole user profile will be reset")

Note that this noon I installed LibreOffice for the first time on the computer in question. The behaviour after reset to defaults is the same as after the fresh installation. Hence there is obviously a difference between Safe mode and factory default.
Comment 4 Xisco Faulí 2018-08-27 14:27:48 UTC 
Select the two options in "Reset to factory settings" and apply changes...
Comment 5 Xisco Faulí 2018-08-27 14:28:07 UTC 
OTOH, Does it work if you disable OpenGl ? -> https://wiki.documentfoundation.org/OpenGL
Comment 6 Peter 2018-08-27 14:43:16 UTC 
I played a little bit around.
I checked "Konfigurieren/Hardware-Beschleunigung deaktivieren (OpenGL, OpenCL)" (translates roughly to "Deactivate hardware acceleration" and chose "Änderungen übernehmen und neu starten" ("save changes a restart").

Now it seems to work permanently.

What seems odd: If I start in safe mode again, the tick has gone away. Nevertheless, it is still in effect.
After "reset to factory defaults", the flawy behaviour comes back.

As a conclusion:
1. The tick doesn't reflect the state of hardware acceleration. This isn't a lie because an already deactivated acceleration must not deactivated again. But I understand it as "on every startup, please don't use hardware acceleration".
2. On the configuration that happened to be the one of my computer, the factory default "hardware acceleration" seems to do bad things.

The original reason for this bug report has gone away, but there are some leftovers, hence I don't want to close this report. I don't know what to do, so I decided to set it to "unconfirmed".

Thanks, Peter
Comment 7 Peter 2018-08-27 14:45:35 UTC 
"and restart", of course. Not "a restart"
Comment 8 Peter 2018-08-27 14:51:12 UTC 
The sentence should read: "This isn't a lie because an already deactivated acceleration does not need to be deactivated again."
Comment 9 Xisco Faulí 2018-08-27 14:57:37 UTC 
This seems to be an OpenGL problem then...
Comment 10 Peter 2018-08-27 15:09:07 UTC 
Ok, but if it is ok to disable hardware acceleration, I'm happy with it.

But of course, I don't want to let the developers die stupid.
What should I do? Replace "UI" in the headline by "OpenGL"?
Comment 11 Peter 2018-08-28 12:01:27 UTC 
The computer is a Dell Precision 7720.
As mentioned before: Windows 10 Pro.

Looks exactly like bug 107764

They advise in the bug to update Intel drivers (I am guessing you use Intel gfx hardware) "via Device Manager -> Display adapters -> Intel(R) HD Graphics 630 (or whichever model number) - > Update Driver"

But indeed: life goes on without OpenGL as well.
