Reproduction: 1. Have Writer use the NB tabbed UI. 2. Start LO with SAL_USE_VCLPLUGIN=gen 3. Create a new Writer document 4. As the new document's window opens, try interacting with the tab bar Expected results: * Document pane shows document, with page boundaries etc, in the new window. * NB bar responsive Actual results: * Document pane is black (I'm on a light OS UI and light LO UI) * NB bar is unresponsive * After ~2-3 seconds, document pane re-renders properly and UI becomes responsive Notes: * Doesn't seem to happen with Calc * Happens not only on startup, but when creating additional documents as well * With the class UI, there appears to be a similar phenomenon of , but for something like 0.25 sec - so not enough for me to try interacting with anything.

For what it worth: I experienced this behaviour on every master branch I build, and I suspect the cause is the debugging options in autogen.input.
