HALion 7.5 Sample Editor tooltip contrast bug

HALion 7.5.0.1153 on macOS 26.5.2 (25F84)
MacBook Pro M3 Max, Apple Silicon native

In the Sample Editor, tooltips for the Sample Start/End, Fade In/Out and Release handles have an extremely light background and light text, making them barely readable.

The issue occurs consistently with every sample/project tested and in both standalone HALion and the plug-in.

Switching macOS between Light and Dark appearance does not resolve the issue.
Other HALion tooltips appear normal.

Expected behavior: marker tooltips should have sufficient text/background contrast, consistent with other HALion tooltips. Screenshot attached.

Does any know if there’s a dedicated channel to report Halion bugs?
