Re: [darktable-user] Sticky mouse?

[Niranjan Rao]

My observation is same, never had problem with earlier releases or any 
other software.


I don't use Gimp, but I think I would have noticed accidental drag and 
drop for any other software. A simple mouse move ends up dragging image 
from darktable or changing properties of module.


I believe chromium uses GPU behind the scenes - at least based on 
command line options and other pointers in source code. That one and any 
other programs I normally use don't exhibit this behavior. If mouse 
button is stuck, chromium would select the region on simple mouse move.


I'll install Gimp and see if I can reproduce the problem.  PC was not 
heavily loaded. I had barely opened one image from film strip at the 
bottom and was planning to choose one of the modules after adjusting 
exposure. Moving mouse around caused exposure module to go berserk and 
moved every slider. I did switch to other programs to see if I can 
reproduce and if it's mouse problem with no luck.

Niranjan

Have you observed the same with other programs
using opencl? I think Gimp could be a
candidate; try to keep it busy for a while and
see if that happens again. If so, my first
guess would be to blame the video driver and/or
the version of the x server. Is there a version
you could update to? Anyway, you may increase
the chances of a sensible answer posting this
question on an ubuntu list.

Re: [darktable-user] How to validate ?

[Jack Bowling]

If you get in the habit of clicking on the image itself before going on 
to the next one, the crop is applied.

There is no explicit validation, crop should be applied when you 
leave the

module, 

Remco


Thats true for the Module "crop".

But the module "crop an rotate" has a bug:

When you go back to the lighttable directly after cropping in the 
picture the result is not applied.


You have to click on on top of the "crop and rotate" tab to close it, 
then go to lighttable.

[darktable-user] Sticky mouse?

[Niranjan Rao]

Greetings,


I have noticed this behavior only for darktable on Ubuntu 20.04. Every 
now and then darktable starts reacting as if I'm pressing and holding 
down my left mouse button. Many times, this results into many unwanted 
changes even when just traversing around modules.



My first instinct was mouse button had gone bad. But any other 
application does not show similar symptoms. For example, right now, 
writing this email in thunderbird does not result in any unwanted 
selections or other effects of any mouse button being down.



Usually a reboot solves the problem. Restarting darktable does not help. 
I've a laptop and both touchpad and external mouse show this behavior. 
I've command line scripts that can enable/disable either of them and 
have tested the behavior independently for each device. I find it very 
hard to believe both devices going bad at the same time and problem 
getting resolved after reboot apart from the fact that issue happens 
only with darktable.



Anyone else noticed similar behavior? Any solutions?


Regards,


Niranjan

There is no explicit validation, crop should be applied when you leave the 
module, provided it is actvated (small icon right of the module should be 
highlighted in history)
