Description: Any Component of LibreOffice (including the "launcher") hangs on startup due to an issue with OpenCL (works fine when OpenCL is turned off). OpenCL was on by default for me, so with a fresh installation LibreOffice was not working at all for me. My OpenCL-Info is below. Since this is on a laptop with nvidia optimus: It doesn't matter if I choose to start LibreOffice with my Intel integrated graphics or the dedicated nvidia GPU. Cheers!

Have specified hardware 2. Have OpenCL turned on 3. Start any component of LibreOffice Actual Results: LibreOffice hangs (inactive) and produces high CPU load Expected Results: LibreOffice just starts normally (I read there's a blacklist for non-working OpenCL devices/drivers? So maybe in this case the expected result would be that OpenCL is turned off per default with this particular OpenCL configuration?)

did you try upgrading to 5.4.4? is the issue still present?
(In reply to tommy27 from comment #2) > did you try upgrading to 5.4.4? > is the issue still present? I did not realize 5.4.4 was a stable release as well, my bad. I uninstalled 5.3.7 and installed 5.4.4, OpenCL appears to be off by default after the installation, LibreOffice started normally.
ok, but what happens if you enable it? do you still experience issues?
(In reply to tommy27 from comment #4) > ok, but what happens if you enable it? > do you still experience issues? Yeah, it doesn't work for me. When manually enabling OpenCL, the LibreOffice "launcher" (I'm not sure how it's officially called) goes through the green splash-screen, then opens an empty LibreOffice window and hangs. When opening Writer or other tools directly, it hangs at the green splash screen without the "splash screen progress bar" visible.
I have to admit though I've always had issues with graphics-intensive programs on this particular machine, went through many different drivers and major windows versions, it's still unresolved. Maybe my machine just does weird things when asked to process anything on GPU. I don't 100% trust it anyway.
Hi Simon: > installed 5.4.4, OpenCL appears to be off by default after the installation, > LibreOffice started normally. Sounds like the black-list is doing its job then =) Thanks for attaching the log - can you report your version of Windows too ? > I have to admit though I've always had issues with graphics-intensive programs > on this particular machine, went through many different drivers and major > windows versions, it's still unresolved.

Could easily be a H/W issue then I guess; certainly we don't do anything that should hang your GPU, it seems we don't enable CL on this machine by default. Thanks for filing though ! =) and always good to keep up-to-date with versions.

Sorry for not replying earlier, I run Windows 8.1 pro, 64 bit, build 9600. Thanks for your support and an awesome product in general! I really appreciate it.
