Summary0013363: Repaint backlog / lag when resizing text frames
DescriptionWhen dragging a text frame to resize it, each mouse move event calls canvas repaint(). The mouse events can occur faster than the repaint causing a huge backlog of input events.
Steps To Reproduce1) Have a slow computer (running Linux?)
2) Start Scribus and create a document
3) Create a text frame.
4) Start a drag to resize the frame and move the mouse around the screen for 10 seconds. Notice the repainting is lagging behind severely.
5) Release the mouse button and watch for the next few seconds as your text frame continues to resize.

Followup: this isn't just limited to the resize gesture. With the freehand drawing tool I was able to generate a backlogue of events which kept being drawn for nearly 5 minutes after I released the mouse button.

Some gestures do not seem to be affected -- the selection tool and magnifier do not show this issue; however the pan gesture does.

The indicators on the rulers and status bar reflect the location currently being drawn, not the mouse location.

I'm not sure if it's related to this issue, but the scroll wheel behaviour is also extraordinarily sensitive, both for scrolling and zooming.

I've tried this on Ubuntu MATE 15.10 beta as well, and am getting the same outcome. This issue is not present in 1.4.5

I have two mice, a Microsoft Compact Optical Mouse 500, and a Mad Catz RAT3. The MS mouse is less laggy than the MC. My PC has a 4.2Ghz processor and 16GB or RAM, so this is not down to the the computer's power. It certainly looks like a mouse-polling issue.

Cannot replicate this on openSUSE 13.2 with current 1.5.1svn. Built with Qt 5.4.2.

I'm wondering what the reporters are using for video cards and drivers. I'm using an Nvidia card with the proprietary drivers.

I have two cards installed, an Nvidia GTX 650Ti which I have my screen plugged into, and an Nvidia GTX 770 which I use for CUDA only.

The black box that shows the mouse coordinates also drags behind, so the whole thing looks a bit silly and is unusable for serious work.

@marcellarius could you possibly test with a more recent version of Qt? (Qt5.5.1) ?

Problem still exists with Qt 5.5.1 and Scribus r20705.

Changing this value does not affect the buggy behaviour.

I can confirm this behaviour also. Looks like it's Qt to blame. Keep seeing this for at least two latest Ubuntu releases.

I think the little black box mouse tip with the x/y location that pops up when dragging is doing something that slows everything else down. When I do a fast drag that finishes before the box can pop up, everything is very snappy.

Is there any way of turning off that black box?

@danillius can you provide a screencast or animated gif to show what you're talking about?

@vlada I'll take a look upstream to see if there's an open bug related

Can't seem to find an open ticket related. Any help would be appreciated.

Turns out that was a false lead on my part. When I wiggled the middle mouse button for a while to move the whole page around, Scribus lagged behind by several seconds. So, once my mouse stopped moving the page was still jiggling around. Clearly the black box is not the issue.

Turning rulers off improves situation, at least for panning. But creating of objects is still leggy and slow.

This needs to be tested with Qt5.6 to see if there is any improvement

This seems to be window manager related.

The symptom was not present on a similar spec system running KDE. I've done some further testing, and on my computer it works fine if use a different window manager (I tested with Fluxbox), or if I disable compositing in MATE Tweak.

Thanks @marcellarius

Do you mind creating a an upstream bug to said specific Window Manager to track this bug?

reporter   ~0039120

It's not specific to Marco (MATE window manager), I see the same problem with Compiz. I haven't been able to test on KWin/Unity/Gnome 3 with compositing because they don't support this hardware; I'll try to reproduce on a more capable machine.

Sorry for the delays, life's been busy and it's taken a while to get everything set up again after filesystem corruption nuked my system :(

The issue seems to be resolved in SVN trunk using Qt 5.6 (from Qt website).
