Hi,

I'm having problems with the Arduino IDE:

• When I open the IDE through the start menu, the IDE works normally,
• But after opening through the sketch (* .ino file), when using the shortcut "Ctrl+/", the IDE adds an additional bar.

The additional bar is inserted wherever the cursor is, if a block is selected to be commented, then the additional bar replaces the entire block.

Examples of the problem:

Initial code:

void setup() {
 // put your setup code here, to run once:
 
 }
 
 void loop() {
 // put your main code here, to run repeatedly:
 
 }

Commenting with cursor before "void":

 ///void setup() {
 // put your setup code here, to run once:
 }
 
 void loop() {
 // put your main code here, to run repeatedly:
 
 }

Commenting with cursor before "setup":

 //void /setup() {
 // put your setup code here, to run once:
 }
 
 void loop() {
 // put your main code here, to run repeatedly:
 
 }

Commenting the "setup" routine block:

 ///
 
 void loop() {
 // put your main code here, to run repeatedly:
 
 }

O.S.: Linux Xubuntu:

$cat /etc/os-release
