Description Andrey Loskutov CLA 2020-08-18 05:41:31 EDT 
RHEL 7.4 (GTK 3.22)

In the recent I builds I constantly observe that the "vertical resize" mouse pointer is not disappearing, and remains "sticky" while it should be already changed to a "usual" pointer.

It comes and goes, and it seemt that happens after resizing view area vertically (to make lower part stack higher).

Must be regression in SWT, I don't see it on Windows.

Probably regression from bug 565903, but I'm not sure, haven't bisected this yet.

I've attached screen recording how it looks like. Sounds like the "resize end" event is not properly handled now.

Paul, Alex, we should fix this for M3 or RC1. This is really annoying.

This is a regression from Bug 562536, a Gerrit to fix it is already available attached to that bug.

Thanks Rolf. I haven't seen this on Windows, so I've assumed that this is GTK only regression.

Hello, I don't think this is a regression due to bug 565903. This is because the changes made to SWT for that bug was GTK4 specific and if I create a child Eclipse from the current master of SWT I can't reproduce this. I'm not sure why it is only seen on GTK though, might be how cursors are updated on different platforms.

Yes, this is not GTK only regression, root cause is bug 562536.
