libreoffice strange behaviour

Hi
first of all I like to say that a appreciate very much this distro, Thank a lot!. It is almost perfect for me. The only issue a have been dealing with for quite a while is a strange font behaviour of LibreOffice. I had to install it to access a lot of odt, odp, ods and odb files a have. When zooming in/out some fonts become bold inside a word and even in the app menu. Some time 80% is ok, 90% is a mess or in any other % . This is quite annoying and happens only with this app. I tried several edition of LO but none of the solve the problem. In other distros I used (mint, suse, debian) I never had such a thing. I very much appreciate if some one can explain why that happen or (better) have a solution for it.

Try this two things:
1. Try diferent graphic drivers (settings >> aditional drivers...)
2. Try WPS office (you have link for it on our ChaletOS main website >> recomended apps or blog)

Hi Dejan
Thank's for your reply.
I will try other drivers and let you know if that solved the problem.
Regarding WPS unfortunately it can't handle odt, odp, ods and odb files. I see the point in having WPS as a "bridge" for those who come from windows world into linux. But for me at the moment it is useless.
Beside this minor issue, I must say that ChaletOS is a wonderful distro! nice, clean, fast and stable. You did a great work.
Best regards

Hi
Just to update the issue...
I tried diferent card drivers but the problem is still there. A test was made in two other machines (acer-one and a generic desktop). Unfortunately I found also the same behaviour. Here are links to the print screens (zoom at 100%, 90% and 75%)

I'm just a regular user, but if there is something I can do to help solving that issue I will do my best.

Thanks
