Description Simeon Andreev CLA 2018-04-19 03:25:16 EDT 
Created attachment 273679 [details]
Resizing an SWT table can lead to pixman_region32_init_rect: Invalid rectangle

See attached screenshot.

Errors are:

*** BUG ***
In pixman_region32_init_rect: Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug

To reproduce in Eclipse:

1. Start Eclipse from command line.
2. Open Problems View.
3. Resize Eclipse window until the table in the Problems View is not visible any more.
4. Observe messages printed on standard error.

I observe this e.g. with:

Eclipse SDK
Version: Photon (4.8)
Build id: I20180304-0800

RHEL 7.2
gtk3-devel-3.14.13-16.el7.x86_64

I also observe this on RHEL 7.4 (GTK 3.22.10)

I still see this exact error on latest 2019-06 eclipse, on Fedora Core 30.

Can we reopen this?

What are the steps to reproduce? Is it the exact same error, or some other GTK warning (we have several)?
