Test program source and makefile
The following commit seems to have broken XFixesGetCursorImage functionality for animated cursors:
Steps to Reproduce:
1. Build animated cursor generator demo (attached)
2. Start the program and click in the window to start the animation (it animates for 30 sec and changes the pointer back until you click again or exit). This will spawn a thread that continuously calls XFixesGetCursorImage and prints the cursor width and height.
3. In the terminal window where the application was launched, note the width and height of the cursor.
Actual results: Width and height are 1
Expected results: Width and height should be ~24 with valid image data.
Once this issue is root caused and the fix is determined, I'd like to request that the fix be put into a z-stream errata for 7.4, and depending on the timing, a 7.5 z-stream errata.
Any chance this issue also exists in 6.9?
Think I know what's going on here, devel ack (and fine with doing this for 7.4.z too).
I've uploaded a test xserver build here:
That's built against 7.5 but I believe it should also install and work on 7.4.
I tested on two RHEL 7.4 systems with both the sample program and HP RGS and animated cursor images are now functioning as expected. Looks great!
This was opened as a regression. From this I was guessing this was working in RHEL 7.4. Please confirm the last release this was working.
If this is not a regression from RHEL 7.4. Please confirm the last release this worked correctly.
If this is required for a Z stream. Please confirm what a client would see in the field. Please confirm what it would mean if this waited for RHEL 7.5.
Yes, this is a regression from 7.4.
The customer definitely wants a z-stream fix for this issue. HP would like to see the fix added in 7.5.
Here's the comment from the customer who found this issue:
"We’ve reproduced this problem in AWS environment on g3 instances. We’re seeing a problem when the s/w uses system animated cursors.
The configuration we’re using is RH 7.4 with RGS 7.4. The current image is running the following version of Xorg server:
$ rpm -qa | grep x11-server
There’s 1.19.3-11.el7_4.1 version available for upgrade using YUM.
For the fix, it would be preferable to have it in RH 7.4 branch because the configuration is rather complex and all the components are interdependent, so a change in OS version could be time consuming until we stabilize the environment. As we’re close to our release and we’ve done most of the cloud testing using RH 7.4 OS, it would be problematic if we switch to RH 7.5."

> Yes, this is a regression from 7.4.
Strictly speaking this is a regression from 7.3. The offending patch was added in 1.19.3-7.el7, 7.4 contained 1.19.3-11.el7. It absolutely warrants fixing in 7.4.z.
