Hello, Could test a Linux Ubuntu system and a Raspberry Pi (PiOS). The bug is not present. It's a Android only issue, likelly due to Qt repaint bug (there's many in Qt 6.9.0, like https://bugreports.qt.io/browse/QTBUG-133549,...hopefully it will fix this issue if resolved in a next Qt release)

Sorry, posted a reply while not being logged... I had the opportunity to do more testing: Both qwt 6.2.0 and 6.3.0 works fine with Qt 6.2.2 Both qwt 6.2.0 and 6.3.0 has the display issue with Qt 6.9.0 So this is definitely a regression due to Qt upgrade from 6.2.2 to 6.9.0. Jean

Hello, I'm planning to test Linux later, I'll let you know if the problem is visible here Did not try 6.3 with previous version of Qt, but I doubt it would have the bug as I see a similar issue even when not using Qwt (https://bugreports.qt.io/browse/QTBUG-136220). I's a Qt 6.9.0 issue I bet. But with Qwt, it really makes the whole widget not behave right. The only way I found to have the view be updated was to change phone orientation. Without Qwt, the screen ends up repainting itself when user...

Painting issue under Android with Qt 6.9.0

Just updated my environment to migrate to Qt 6.9 and Qwt 6.3.0 and I can now confirm it's fixed for good. Thanks a lot for this great library, Jean
