The flickering happens when:
- qgis window grabs/losts the focus
- mouse enters/exits map canvas but ONLY if qgis window does not have the focus
I'm on git master up-to-date (2011-02-14) (last commit 1dfc3b7a293c40f3d10386cc620dee2322dd152b).
Versione di QGIS 1.9.90-Alpha
QGIS code revision 2cea349
Compiled against Qt 4.7.4
Running against Qt 4.7.4
GDAL/OGR Version 1.9.0
GEOS Version 3.4.dev
PostgreSQL Client Version 9.1.2
SpatiaLite Version 2.4.0
QWT Version 5.2.2
There is no log from QGIS, no log from Xorg, nor entries in syslog.
Toggling the checkbox "Update" does not have any effect, so flickering is not due to updating the view.
My video card is a Radeon HD 3450, with radeon driver.
I'm on kubuntu 11.10 running kde.
Toggling desktop effects in my desktop manager (kdm) does not have any effects.
Toggling compositing type from OpenGL and Xrender does not have any effects.
It is probably related to issue #4011
