As the mouse cursor hovers over the UI for the formula editor (not checked for other UIs) the images flicker. The flickering is stronger further down the interface (no flickering for first item), looking like an overzealous redraw. It seems to clearing the GUI and begin writing the new draw to the screen before the whole GUI is rendered.

The flickering was already there when this feature was added in 4.1, so adding implementationError keyword. The commit where the flickering became worse is: https://cgit.freedesktop.org/libreoffice/core/commit/?id=a51b7a1c3a7e7cf7b0c733e1dec40288278c1884 author Khaled Hosny <khaledhosny@eglug.org> 2017-03-03 03:15:14 (GMT) committer Khaled Hosny <khaledhosny@eglug.org> 2017-03-03 13:22:53 (GMT) "tdf#103831, tdf#100986: Force using GDI when needed" This commmit brought forth other bugs as well (but it's not directly responsible for those), see bug 107166 or bug 108236.

The problem is older: see comment 1 Hoovering over the Formula dialog will flicker. Not always in the same extend, but it will eventually (depending on LibO version) Also: still a repro with: Version: 6.0.0.0.alpha0+ Build ID: b087e451527f2e497ccab83b63b4f10099bfb8b8 CPU threads: 4; OS: Windows 6.3; UI render: default; TinderBox: Win-x86@42, Branch:master, Time: 2017-10-03_23:43:39 Locale: nl-NL (nl_NL); Calc: CL I can reproduce it also on Linux.

Created attachment 136775 [details] Bibisect log
@Jan Marek You might be interested in this one. It has a timer/scheduler aspect; not sure if it's the root cause, though.

I only checked on Windows, but the flickering is clearly there in 4.1.0.4.
