@Patrick
Xcode instruments shows that cpu time being spend in
_platform_bzero$VARIANT$Haswell in a regular fashion while typing. The link in
comment 6 suggests this not being optimal. The question: is this worth
investigating or should the bug be closed as NOTABUG or WONTFIX

Starting from
The key note here is that we can clearly see that we’re spending the bulk of
our time in _platform_bzero$VARIANT$Haswell. This method is used to zero
buffers. This means that macOS is zeroing out the buffers. Why?

Well unsure what was about exactly. 

Version: 7.6.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 8635c9aa8c6f1078a9e220076d5a08daf30077e8
CPU threads: 8; OS: Mac OS X 12.3.1; UI render: Skia/Metal; VCL: osx
Locale: nl-NL (nl_NL.UTF-8); UI: en-US
Calc: threaded

This is still relatively expensive

Please try this with a developer build from
https://dev-builds.libreoffice.org/daily/master/ [*]. Check with option
Tools->Options->View->Use Skia for all rendering both enabled and disabled, and
when enabled with both Force Skia software rendering enabled and disabled.

And is this a duplicate of bug #120727?

[*] Today's build may still have some rendering problems in dialogs, so
tomorrow's should be better, but even today's should be usable for testing this
bug.

Dear Telesto,

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice
from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information
from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave a comment that includes the information from Help
- About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3) from
https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat:
https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

Confirming with my master build 6.0alpha1.

The main lag seems to appear for me in the handling in bitmap.cxx, line 945:

Bitmap aBmp(GetBitmap(aDstRect.TopLeft(), aDstRect.GetSize()));

which is called by function :

void OutputDevice::DrawDeviceAlphaBitmapSlowPath(const Bitmap& rBitmap, const
AlphaMask& rAlpha, tools::Rectangle aDstRect, tools::Rectangle aBmpRect, Size&
aOutSize, Point& aOutPoint)
