Color Tool not visible with special workspace file

[siegmund]

Hi guys,

I think I discovered a bug.
When I am loading attached workspace, open an arbitrary scene, select a fixture and then trying to open the color tool, no color tool appears.
Ubuntu seems to notice that a new window should be opened (another dot next to QLC+ icon), but it is not visible. QLC+ UI is locked, until I use right click on QLC icon on starter -> "Exit 2 Windows". Then, the invisible color tool window is gone and I can use the UI again.

Interestingly, everything works when using a blank new workspace.

Is there something wrong with this workspace file?

Logs do not seem to display anything related.

QLC+ 4.12.7
Tested on:
Ubuntu 22.04.3 LTS
Intel NUC PC
Intel(R) Pentium(R) Silver J5005 CPU @ 1.50GHz

Best regards,
Lukas

We lack the fixture profile to do some tests, but I can already say that the color preview for a multi-headed fixture is troublesome.

I would say you had another display connected and the tool is displayed somewhere outside the main display.
If that's the case, you need to reset the QLC+ settings and the issue is not related to the workspace itself.

Ah sorry, please find attached

This was not the case, only one display connected.
But anyways, how can one reset the QLC+ settings?

Settings are basically here (platform-dependent)

Okay, but this is global for all workspaces, correct? Because when creating a new workspace everything works fine, even with the fixture in question.

Quickly tested on Windows. Works for me with your workspace. Color tool is displayed in the center of the screen.
I think there is something we're missing here but couldn't understand what exactly.

I quickly tested on Windows as well, there it works for me too...
It feels like this is more a Qt-relatet thingy. Is there any chance to get more debug output? Tried with console option -d 0/3 but only very few lines there.

On Ubuntu 22.04, KDE Plasma (x11) and QLC+ 4.12.8-GIT It works as expected.

Here's Linux too.
No idea what's going on in your Ubuntu. Perhaps look at Qt settings in your

Code: Select all

$HOME/.local/share/

Okay this is really strange. I did a lot of fiddling the xml code to find out that actually the SpeedDial widget in VC is causing the trouble.
If I delete it in the _broken file, everything is back to normal.
If I create a SpeedDial widget in the _works file, everything still works until I re-open the file, then it is broken as well.

I have attached a picture of how the "stuck" Color Tool window looks like on my ubuntu.

In addition, a screenshot of how the color tool looks on my side when opened normally (this is different from your screenshot so just wanted to point this out).

Do you have a GitHub account?
Can you please try the latest build from GitHub Actions?
That looks like a Qt issue/incompatibility

[siegmund]

Latest build from GitHub Actions works as expected. I see the same Color tool as visible for you.
Do you have any indication on when the next release is planned?

[siegmund]

Just realised that this version produces some UI Glitches as shown in attached screenshots, so I guess it won't be released too soon...

Dear all,

this thread is already some days old. But not sure of this has been finally solved for "siegmund". I now have same problem when changing from Linux Mint 21.3 to 22.0. So far what I could found out, The "color select" dialog in m working scenario (Mint 21.3) is the QT dialog. The none working "color select" dialog seems to be the native one. I installed both Linux versions so I can switch between working and none working. If I use the working Linux version "Linux Mint 21.3" I cn crete the issue when starting qlcplus with the paramter " -platformtheme none". Which seems to force the native dialog. But I haven't found a start parameter to force "QT DIalog".
BTW: If I say "none working" I mean same behvior as "siegmund" described related to the "Speed dialer" - see above. Even re- compiling from Github did not help.

Hopefully somebody has an idea.

Kind regards.

Not sure, if somebody still has this issue and is looking for a solution,but I found it in the meantime and want to share it with you. I another forum I found somebody complaining, that after installing Linux Mint 22 Qt ist not properly working. The proposed solution was the following:
1) Install "qt5ct" sudo apt install qt5ct
2) After that add following line to file /etc/environment : QT_QPA_PLATFORMTHEME=qt5ct
3) Reboot system

Exact steps helped with my problem. So hopefully this helps also others.
