SQLdeveloper cursor goes awol

OTG-467455 Oct 5, 2017 8:51 AM

I have recently started noticing a bizarre issue when using SQLdeveloper. The cursor seems to dissapear and when trying to code the characters do not appera where you want them to be. It is like trying to find your way around in the dark.

In all cases the O/S has remained constant (Windows 7 64bit). This has occurred on different VirtualBox platforms (4.1.nn), different Guest O/S like Oracle Linux 6.9 and 7.n and SQLdeveloper 4.2 and 17.n.

Enough RAM. Do notice that after a long time that SQLdeveloper does not repaint the screen properly.

Has anyone experienced this? Does ThatJeffSmith know about these issues as they seem to be reported an various forums?

Your description is kind of sketchy, but mostly likely another symptom of...
SQL Developer 17.3 - Bug with multiline strings?

This regression has been fixed for 17.4 and seems to warrant posting an updated 17.3 release after additional testing. Stay tuned.

Noticed that resizing the SQLdeveloper window brings it back for a while until it decides to go to sleep again. Found this workaround mentioned forums outside of the Oracle community.

How does one resolve this permanently?

Sorry, I did not read your post carefully enough...
This has occurred on different VirtualBox platforms (4.1.nn), different Guest O/S like Oracle Linux 6.9 and 7.n and SQLdeveloper 4.2 and 17.n.
If it is occurring everywhere, with different versions, then I have no clue. My earlier post pertains only to 17.3.0.

Hi Gary,

I also came across the discussions around the multiple monitor issue in some research I conducted. The virtual machines I run on Windows 7 64 bit are set to single screen mode. Even with this setting the problem happens when running SQLdeveloper on the Linux guest. If I run SQLdeveloper directly on the Windows host and link to the VirtualBox Linux Guest then there are no problems. Also picked up on the issues with 17.3. Have not upgraded yet. All software is up-to-date. All yum updates applied to Oracle Linux.

I must mention that this issue can at times be intermittent. I notice you mention a bug fix in 17.4. Is there any indication as to when this version will be released for general use?

The fix for the above-mentioned 17.3 bug will also be released as a 17.3.1 full download. As the 17.3.0 worksheet and code editor behavior is quite annoying in a couple of cases, I would expect that very soon, perhaps as early as tomorrow if no other regressions from 17.2 get bugged.

The bug, however, does not seem related to your issue -- it only applies to 17.3. Since the multiple monitor scenarios related to bad Windows updates do not seem applicable either, it could be your video driver.

And in terms of Linux distributions, the comment about change cursor color and thickness may be a better workaround for you...
Caret / Cursor problem on 4.1

It mentions a window resizing workaround also, but changing cursor color and thickness better qualifies as "permanent", I think.
