[Libreoffice-bugs] [Bug 108526] New: Calc not Win10 DPI aware, display elements missing on 4K screen

[b***@bugs.documentfoundation.org]

https://bugs.documentfoundation.org/show_bug.cgi?id=108526

Bug ID: 108526
Summary: Calc not Win10 DPI aware, display elements missing on
4K screen
Product: LibreOffice
Version: 5.3.3.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: libreoffice-***@lists.freedesktop.org
Reporter: ***@arno.com

First, there is a solution, read on...

I am running a Surfacebook 3000x2000 resolution with an external 4K monitor
4096x2160 resolution.

When I open calc every third horizontal cell separation line is missing from
the display. At first I thought this might be a feature, but later realized
it's a bug.

The "solution" is to set Windows LibreOffice application properties to
"Override high DPI scaling behavior" "Scaling performed by: System". With
this property set all calc row lines reappear.

This new Windows 10 "feature" is messing up many more mature Windows products
on high DPI displays. I'm finding many applications have a file like
"scalc.exe.manifest" which contain XML like:

<asmv3:application>
<asmv3:windowsSettings
xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">
<dpiAware>false</dpiAware>
</asmv3:windowsSettings>
</asmv3:application>

The critical part is "<dpiAware>false</dpiAware>" to allow an application to
display as it has on prior MS Windows products.

I adjusted this setting on the LibreOffice launcher and now everything looks as
it has on earlier versions, and matches appearance under Linux.

Thank you for reporting the bug.
it seems you're using an old version of LibreOffice.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

LibreOffice in general has several problems on high DPI screens ranging in
severity from minor nuisance (Calc missing lines) to crippling (Impress
presentation mode).

These display issues may require a fairly senior software developer to overhaul
the LibreOffice display architecture framework. i.e. in my opinion this isn't
a "simple software fix".

Seems like the relevant element is dpiAwareness for Win10 version 1607 or
later:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa374191(v=vs.85).aspx

Can you check if permonitor or permonitorv2 works, or only unaware does?

How would I check permonitor, permonitorv2, or unaware?

Here is what I did; I set the LibreOffice5.4.2.2 x64 desktop shortcut
"Compatibility" to "Override high DPI scaling behavior" to "Scaling performed
by" [Application], [System], [System (Enhanced)]. All three modes seem to work
with SCalc.

Turn off "Override high DPI scaling behavior" and the problem of missing or
extremely light horizontal cell lines reappear.

Either of the "System" compatibility modes is desirable. The "Application"
setting makes the application look like it's been zoomed to 2x... large and
gross.

BTW, the adapter I use for the HDMI 4K output is the Microsoft
recommended/supported "Cable Matters DP 1.2". The Surfacebook 4K screen
[3000x2000 @150%] shows lines as I expect to see them. It's the external
display, 43" 4K [4096 x 2160 @100%] monitor driven through the Cable Matters DP
1.2 which is experiencing the Lost Lines and/or missing icons issue.
Overriding the DPI behavior makes the problem disappear.

Setting the 4096 x 2160 external monitor to 150% makes the lines reappear.

Oh, I don't know how the manifests works, based on the description I thought
you managed to set that somehow. Either way, thanks for the details!

Version checked 6.1.3.2 (x64)

Missing lines problem resolved.

Checked scaling at 100%, 125%, 150%, 175%, 200%, 225%, 250%, 300%, 350% on the
43" 4K [4096 x 2160 @59Hz] monitor. Also performed a quicker test on the
primary Surfacebook 3000x2000 display.

Looks like you nailed it for Calc! This bug is resolved on my hardware.

========
I checked Impress "Bug 106526 - Impress dual head presentation to 4K or QHD
resolution monitor or projector has presentation screen tearing" and that bug
still exists.
