At the moment, very repeatable:
This is from the 10JUN18 nightly “kicad-r10501.72b49accc-x86_64.exe”
Version: (5.0.0-rc2-154-gb82bf7c44), release build
libcurl/7.54.1 OpenSSL/1.0.2l zlib/1.2.11 libssh2/1.8.0 nghttp2/1.23.1 librtmp/2.3
Platform: Windows 7 (build 7601, Service Pack 1), 64-bit edition, 64 bit, Little endian, wxMSW
wxWidgets: 3.0.3 (wchar_t,wx containers,compatible with 2.8)
OpenCASCADE Community Edition: 6.8.0
Compiler: GCC 7.1.0 with C++ ABI 1011
Clicking “b” or “F9 then F11” gets it back to normal.
This may already have been fixed with a newer nightly.
Secondly, I have been using this nightly without issue, until I did a complete wipe of KiCad off of my machine, regedit out every kicad instance and removing every instance of kicad (and settings files) in user folders.
Essentially, it should have been a “clean” installation.
Anyone else have this issue?
