After upgrading from 15.12.3-2 -> 16.04.0-1, the Rectangular Region option lets you select an area of the screen, but does not preview the image, and the saved image is blank. Other options like Active Window, Current Screen, etc. work as expected. https://bugs.kde.org/show_bug.cgi?id=359368 is marked as Resolved Upstream for the Nvidia driver. I use the nouveau driver, and wasn't sure if whatever Nvidia has done will help with nouveau. I tried downgrading to 15.12.3, but Spectacle would not work at all. I assume I would need to downgrade other, related packages.

I read that this bug was fixed in 16.04.1. Something goes wrong, because I have 16.04.1, but the problem persists.
Has been working for me, on Arch Linux. I haven't tried other distros. Name : spectacle Version : 16.04.1-1 Description : KDE screenshot capture utility Architecture : x86_64 Build Date : Fri 06 May 2016 08:31:23 PM EDT Install Date : Tue 10 May 2016 05:14:31 PM EDT
Never mind, it's a mistake of mine. Spectacle 16.04.1 works correctly with rectangular region. Sorry.
OpenSUSE Leap 42.1, Plasma 5.6.4, KDE Frameworks 5.22.0, Applications 16.04.1. No way! Spectacle 16.04.1 is not able to take a snapshot of a small rectangular region; it works only if the region is big. (nVidia proprietary driver).
Rectanglar Region capture does not work below about 400x300 ish Version 16.04.3 on KDEneon Why is this marked "Resolved?"
Created attachment 100380 [details] Tiny Rectangle Selection This is a tiny rectangular selection. Check with your GPU drivers. Nvidia is a known troublemaker.
Boudhayan Gupta, nothing is resolved or fixed; Spectacle does not work! It is not able to take a snapshot of a small rectangular region; it does not remember previous geometry. During the snapshot, the screen becomes too dark and the cursor becomes invisible. I don't understand why all these bugs are marked as RESOLVED, FIXED. And I don't understand why Spectacle needs to deal directly with the GPU drivers; an application must be driver-independent. It is ridiculous that in Plasma 5, KSnapShot is considered obsolete; it works perfectly and Spectacle does not work at all.
All of them are fixed. 1) Previous geometry can be remember as of KDE Applications 16.04 2) You can switch the mask colour to a light background as of KDE Applications 16.04 3) If you're using nVidia drivers, you may have problems with the smaller rectangular selection sizes. This is not Spectacle's fault but Qt5's - KSnapshot works here because it's still based on Qt4. Presumably one of Qt or nVidia will fix their problems at some point in time. Please ensure you're running an up-to-date version of the software before reporting bugs.

Have you tried clicking the arrow next to the Save and Exit button and then clicking Preferences?
Yeah using nvidia driver here, thanks for the reply Boudhayan. I've had numerous issues with nvidia drivers higher than 340 with the newer 4.4 kernels. I don't have time to validate this right now, but I'll try reverting back to 340 and see if the issue continues. IMO, the latest nvidia drivers are crappy/buggy
