There are similar issues with the dialog that comes up when you try to modify a hidden layer. This might be fixed by #1269 because of the modifications to how tablet and mouse events are handled.

@Kaikogf @scribblemaniac I've tested this with Jan 9th build. The mentioned issue doesn't seem to occur in my case, however I can't close the about dialog by pressing the [X] button when using a stylus.

Can you test this? If it happens to you as well we'd make a new bug report for that issue separately and close this one as fixed.

I cannot reproduce this either with Linux 19.10 + Huion H430P on either v0.6.4 or on master.

@Jose-Moreno
I cannot reproduce your [X] issue. I tested this with the last build [25fev2020] and it is fixed since there is no sight of the issue. I am closing this and if you experience an issue you can open a new post as you suggested.

Thanks! :+1:
