I installed 5.0 beta1 (LibreOfficeDev_5.0.0.0.beta1_Win_x64.msi) and the first think i found after few seconds of usage is a flickering bug at all drop down menus. When i press on "file" or any other buttons above in calc, writer, ... and move the mouse down, the dropdown menu with all of its functions is flickering. Also the pressed button get the color white. It was not white before. White is nearly impoissible to read on the default gray background. The System is windows 7, 64bit, most recent stable AMD gpu drivers on an AMD HD7xxx card.
Same on 32bit: LibreOfficeDev_5.0.0.0.beta1_Win_x86.msi
Seems fixed now… reopen if it’s not the case after testing a newer daily build. *** This bug has been marked as a duplicate of bug 91366 ***
