Seen in Linux with Intel Graphics. Possibly this is different in other architectures. With LibO 5, the screen often does not refresh unless one scrolls up and down a little. Seems to be triggered by "OpenGL rendering everywhere".
This happens during *edit*, not *presentation*
What is your kernel version? What graphics card exactly and what driver?
What Linux distro?
Still continuing with 5.0 RC4 or RC5?
Screencast would be a bonus :)
Linux version 3.19.0-25-generic (buildd@lgw01-07) (gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13) )
In fact, the ubuntu vivid standard kernel
Intel Gen8 Graphics
VGA compatible controller: Intel Corporation Crystal Well Integrated Graphics Controller (rev 08)
In fact the ubuntu vivid standard graphics stack
Working without OpenGL rendering everywhere seems to workaround the issue without any apparent problem.
Will check with newer LibO as soon as possible.
I know this is an Impress bug, but I found LO5 Writer immediately unusable because of screen refresh issues. Major portions of pages would disappear and not come back, and the menus would go blank. Not sure if I'm seeing this same bug, but this one seemed close. I had to go back to 4.4.5.
Ubuntu 12.04. 3.13 kernel. GeForce GT 430. Nvidia Driver 331.113.
I'm not sure where the "OpenGL rendering everywhere" setting is to be found.
We've fixed so many bugs around OpenGL; please re-test with 5.1.0 RC2 (due next week) and re-open if you still get this.
Tools->Options->View has the OpenGL options on it - but on Linux it should be off by default.
