Comment 2 V Stuart Foote 2017-07-29 04:19:06 UTC
Noticed this last couple of TB39/42 builds when moving or resizing the LO window frame.

This seems to relate to lo/system timer rework for bug 109123 [1], on Windows 10 Pro 64-bit en-US with TB39 20170729 build 3c75009a677ae950105a65c699b16caf72b516b0

Still seeing this even with this commit present

Annoying more than anything, seem to be able to safely Ignore...
