Libreoffice Hardware Acceleration Software For Windows

If you have any pointers for setting up the Eclipse IDE for debugging LibreOffice C software for Windows and Linux LibreOffice development, I could use this too.

Dual monitor setup, click on Start from First Slide - F5 and presenters view shows up fine on Surface Book display, but 4K monitor used as presentation display shows junk.

I tried LibreOffice 5.3.0 x64, 5.3.0 x86, 5.2.6 x64, 5.2.5 x64, 5.1.6 x64, 5.0.6.3 x64, 4.4.7.2 x86.

All failed the same way.

Swapping screens changed behavior slightly, but the presentation screen was always messed up, the presenters screen always rendered correctly.

I tried OpenOffice 4.1.3 and both displays looked right, except the presentation display was on the smaller display and the presenters window was on the large display with no way to swap the two as there is in LibreOffice.

A cursory code look, I would suspect trouble starts at in the addView() routine when the second call to add the Presenters screen is called.

I see a number of design patterns used which arent in my background, so a developer more practiced in these patterns and this specific code area will need to do the debugging.

I hope it will be relatively straightforward for a developer to discover why this code fails on a dual 4K screen and works fine on a dual 1080p screen set.

My guess is there is a constant or two for memory allocation which needs to be updated from 1920x1080 to 4096x2160 so memory isnt overflowed and corrupted by a pointer passing a boundary and writing where it shouldnt.

This is based on watching the screen initially paint right, then be overwritten and corrupted by what I assume is an update pass.

This code will not work on todays current batch of 4K laptop screens with auxiliary 4K monitor, like what Im running.

Im working on my presentation now, in Impress, and Id really like to use LibreOffice Impress for this presentation.

If you would like to become familiar with the code in general, Chris Sherlock has this work-in-progress book.

The information on submitting code and getting in contact with developers (on IRC and mailing list) is here.

Im an electrical engineer working on a High Speed Electronic Design presentation.

This presentation will take most of my time between now and my deadline.

So here is what I can do beyond what Ive done so far; I need to finish my presentation first, which I expect will take me close to my deadline.

Then if there is time, I can try to get up to speed on and fix the LO display driver code.

Help from anybody else to address and repair this is appreciated.

The risk is I may not finish my presentation in time to fix my LibreOffice problem for the presentation I must complete.

I hope someone with necessary skill and time will pick this up and fix it prior to when I might have time.

This is just one more piece of chaos, and I may not have the bandwidth to also add this to my efforts.

Thank you for the links, I did look at them, and will keep this Windows based project in the back of my mind.

Windows is where Im having the problem, so it makes sense to work on the problem in Windows, but Id also like to try the builddebug in Linux.
