StackOverflow in CommitTable.layout() with new experimental resolution scaling preference

[Bananeweizen]

Version

7.1.0

Operating System

Windows

Eclipse version

2024-12

Bug description

I have seen the following StackOverflow in 2 different instances by now. Both of them happened after logging in to a hibernated Windows session. Both instances have the new dynamic resolution scaling enabled: https://eclipse.dev/eclipse/news/4.34/platform.php#rescale-on-runtime-preference and happened while running on an external monitor connected to my laptop. The history view was not visible at the time of the errors (but rather stacked in a view stack).

Actual behavior

eclipse-platform/eclipse.platform.ui#2461 is the resolution scaling change mentioned above.

[tomaswolf]

I guess the problem is

egit/org.eclipse.egit.ui/src/org/eclipse/egit/ui/internal/history/CommitGraphTable.java

Line 307 in cd8c66d

rawTable.addListener(SWT.Resize, event -> layout(rawTable));

layout() is called when the table is resized, but re-layouting may cause the table size to change. Don't know why this is only a problem with this experimental auto-scaling. In any case I believe the minimal fix would be to attach the listener to the composite containing the table:

tableContainer.addListener(SWT.Resize, event -> layout(rawTable));

I'm not set up to run EGit against the latest platform, so I cannot verify myself.

[Bananeweizen]

Thanks @tomaswolf . I'll try to not forget this issue, since I can only test the change with the same setup in 2 weeks after the holidays.

[tomaswolf]

@Bananeweizen Did you have time to look at this?

[tomaswolf]

@Bananeweizen Does this still occur with EGit 7.4.0 and current Eclipse (2025-06 or 2025-09)? If not, I suggest to close this.

[jcompagner]

it still does occur with 7.3, couldn't test it yet in 7.4

But this does also seems to be related by the scrollbar, that is constantly popping in and out, so if we make the view a bit bigger so it doesn't draw the scrollbar it works.
