Hi Renato. The description of your issue is so similar to mine and others that
I'm not convinced your video hardware is at fault. I'm also using KDE under
Mageia 5 (but with LO Fresh 5.1.4) and this issue still persists for me. As a
possibly more satisfactory workaround, I recommend checking to make sure that
your sub-pixel rendering is disabled:
KDE System Settings > Application Appearance > Fonts > Use Anti-Aliasing
[Configure...]
If it isn't, disable it, then re-enable your hardware acceleration, and see if
this improves your user experience. If it does, you'll likely notice a slight
degradation in the appearance of fonts in other apps (notably Firefox), but
given the choice between sub-pixel rendering versus hardware acceleration, I'd
choose to dump sub-pixels in order to keep hardware acceleration every time.
For a more verbose treatment on all this, see my step-by-step report at Bug
69011. Note I wrote that report while running Mageia 3 and much of the
flakiness KDE was exhibiting at that time has since been ironed out.
Best of luck.
P.S. I've still got my fingers crossed that when the remaining issues with
OpenGL get sorted and we Linux users can actually enable it again -- for
examples see Bug 97904 and Bug 99299 -- all this will be just an ugly memory.
In Bug 97904, comment 4, Caolán committed an OpenGL patch to 5.1.2, but I
haven't noticed a difference so far. I'm hoping it works in the 5.2.x branch.
