Was using Today i have tried to update to and after the update fonts in Calc are fuzzy and menu flickers when going through it. Looks like another OpenGl/video issue. I had to disable OpenGL through a registry after 5.1 update to make my fonts look ok and menus show text. OpenGL is still disabled (it says so in the View menu).

At 5.3.2 font rendering on Windows builds has been moved more completely to DirectWrite/Direct2D calls replacing remaining GDI only calls and its grayscale anti-alaising . It brings the non-OpenGL "Default" rendering to parity with "OpenGL" accelerated rendering providing more reliable cross platform text layout and shaping--but at the expense of some rendering quality on Windows builds for folks used to the "Default" rendering. ClearType anti-aliasing is not implemented.

Believe additional work is needed on the DirectWrite based font rendering and anti-aliasing, but the GDI and its grayscale anti-aliasing calls will likely not be restored.

See the bug report tdf#106990

Cause of the UI flicker affecting only "Default" rendering does not appear to be a driver issue, while users of "OpenGL" accelerated rendering are not affected. See bug report tdf#105863

Could be the notorious LO user profile corruption. Make sure LO is completely down, then rename the profile folder as guided in

Could as well be graphics driver issue.

No this affects many users. Its a bug from LO

Thanks for the links to bug tracker tickets. I'm starting to strongly debate whether i should still be using (and donating money) LibreOffice. If i could just subscribe to Office 365. First i had to mess with registry and disable OpenGL after 5.1 for LO to even show text, now this. And comments from devs are like "you use windows, it's you problem"..
