New Gerrit change created: https://git.eclipse.org/r/78204
The change https://git.eclipse.org/r/78204 does not fix the root cause of the bug but makes the symptoms less severe.
Can you provide steps or a test case?

Judging by the call stack this problem may have the same root cause as bug 506113 - the change https://git.eclipse.org/r/#/c/79134/3/bundles/org.eclipse.swt/Eclipse+SWT/gtk/org/eclipse/swt/widgets/ProgressBar.java

(In reply to Dani Megert from comment #10) > Why is this only fixed in R4_6_maintenance? Note that our process is to fix > it in master and only consider a backport when it was working for some weeks > there. As explained in the commit, this change is intended for the 4.6 maintenance stream only. The 4.7 development stream contains a more general protection mechanism guarding against exceptions in SWT event listeners. That protection mechanism is based on bug 499010 and cannot be backported to R4_6_maintenance branch due to dependency on JRE 1.8. Please notice that the bug is not fixed. https://git.eclipse.org/c/platform/eclipse.platform.text.git/commit/?id=58541c443c1a81178e859157dcd567915728f643 prevents caret from disappearing but doesn't fix the underlying issue.
(In reply to Sergey Prigogin from comment #11) > As explained in the commit, That's the pity of having Gerrit and Bugzilla - comments are split between two systems.
The problem doesn't seem to happen anymore after the change https://git.eclipse.org/r/#/c/79134/3/bundles/org.eclipse.swt/Eclipse+SWT/gtk/org/eclipse/swt/widgets/ProgressBar.java has been reverted.
