If I disable trayicon in sylpheed-2.3.x, pypanel begins to flicker. This happens on every start of sylpheed, not only in the session I disabled the trayicon. I first thought only restarting pypanel helps, which kills sylpheed (shouldn't happen), but later I noticed that apparently the flicker comes from a *long* list of queued pypanel redraws. So some time after exiting sylpheed the flickering stops. Another thing to note is that an empty icon is added to the tray area, possibly causing the problem, but possibly only another symptom. For now I masked both 2.3 releases, since sylpheed-2.2.10 does not show this bug. Happens on beryl-9999 and fluxbox-1.0_rc2-r2. Reproducible: Always Steps to Reproduce: 1. emerge '>=sylpheed-2.3.0' pypanel 2. $ pypanel & 3. $ sylpheed 4. deactivate trayicon in sylpheed settings 5. (restarting sylpheed does not help) Actual Results: Pypanel begins to flicker and an empty icon is added to the trayicon area. Expected Results: Nothing happens in pypanel.
