Created attachment 171931 [details] Bug document Simply opening the attached presentation without any action in the GUI or otherwise, just letting LibreOffice sit idle, spams the console with ~1500 instances of warn:legacy.osl:20384:20384:vcl/source/outdev/bitmap.cxx:463: CopyBits with zero or negative width or height per *minute*. How to reproduce: 1. Save attachment as circle.pptx 2. Open a (Unix-type) shell 3. date ; lo circle.pptx 2>&1 | grep CopyBits | wc -l ; date In a test I did on my notebook, this gave me ... 21:06:16 CEST 514 ... 21:06:37 CEST There's two issues here: the spamming of the console, but maybe more importantly - what is LibreOffice doing in a tight loop apparently when there is no user action at all?
On pc Debian x86-64 with master sources updated today, I could reproduce this.
Fewer warnings in 24.8. warn:vcl:88607:88607:vcl/source/window/dndeventdispatcher.cxx:137: rejecting drag enter due to missing listeners. warn:vcl:88607:88607:vcl/source/window/dndeventdispatcher.cxx:185: rejecting drag over due to missing listeners. warn:vcl:88607:88607:vcl/source/window/dndeventdispatcher.cxx:185: rejecting drag over due to missing listeners. warn:vcl:88607:88607:vcl/source/window/dndeventdispatcher.cxx:185: rejecting drag over due to missing listeners.

I would focus on the "CopyBits with zero or negative width or height" of the warning and tend to ignore anything else. Is this warning still happening? Note that this will only happen in a debug build.
Note for myself: the warning is in a weird spot. Should be warning if the height or height is out of the drawing area. The truth is, this may not be a huge deal IMO as it could be outside the drawable area for valid reasons... perhaps move it to a SAL_INFO in the correct spots.
This bug originally was about "Simply opening the attached presentation without any action in the GUI or otherwise, just letting LibreOffice sit idle, spams the console with ~1500 instances of warn:legacy.osl:20384:20384:vcl/source/outdev/bitmap.cxx:463: CopyBits with zero or negative width or height per *minute*." This no longer happens for me with recent versions of LibreOffice such as the following, so closing this as WORKSFORME (now).
