Description Michael Weghorn 2025-01-29 22:05:01 UTC 
Steps to reproduce:

1) Start LO with the gen VCL plugin on Linux (SAL_USE_VCLPLUGIN=gen)
2) trigger a tooltip, e.g. by hovering over a toolbar item

Actual result:

A "tooltip" shows up, but it's only a white area with no readable text. (Maybe white text on white background?)

Expected result:

A tooltip with readable text should show up.

    Change alpha behavour of OutputDevice::SetFillColor

Before that commit, a tooltip with black text on light yellow background shows up as expected.
