Switching between linear and page layout sometimes fails #432

Closed guiv42 closed 5 months ago

guiv42 commented 5 months ago

Reproduced with both versions 1.6.3 and 1.5.6, running on Linux (openSuse tumbleweed)

To reproduce:

open a tab
click menu View/Page Layout
click menu View/Linear Layout

then, repeat steps 2. and 3. many times (occurrence of issue is quite low)

Sometimes one operation fails: user action is ignored, layout does not switch Sometimes, 2 successive and fast switches are applied

understood. It's a bit incredible this bug has been there for so long:

display tablature in linear layout
click on menu view/page layout

There, 2 tasks are started in parallel! : switch to linear layout AND switch to page layout Result just depends from the execution sequence

explanation: when one SWT radio button is clicked, it generates an event. But if another radio button of the same group was selected before, it gets unselected and also generates an event

Fix coming soon
